How much computer memory (in bytes) in minimum would be required to store 10 seconds of a sensor signal sampled by a 12-bit A/D converter operating at a sampling rate of 5 kHz?
Answer:
73.24 K byte
Explanation:
Assuming that
N = total number of samples
N = 10 * 5kHz
N = 50*10^3
Also, the total number of bits, T
T = 12 * N
T = 12 * 50*10^3
T = 600 * 10^3
And then, finally, the total number of byte,
B = 600*10^(3/8)
B = 75*10^3 byte
75*10^3 byte = 75*10^3/1024 kilo byte
And on converting to decimal, we will have
= 73.24 K byte
Therefore, the memory required = 73.24 K byte
Suppose the working pressure for a boiler is 10 psig, then what is the corresponding absolute pressure?
Answer:
The corresponding absolute pressure of the boiler is 24.696 pounds per square inch.
Explanation:
From Fluid Mechanics, we remember that absolute pressure ([tex]p_{abs}[/tex]), measured in pounds per square inch, is the sum of the atmospheric pressure and the working pressure (gauge pressure). That is:
[tex]p_{abs} = p_{atm}+p_{g}[/tex] (1)
Where:
[tex]p_{atm}[/tex] - Atmospheric pressure, measured in pounds per square inch.
[tex]p_{g}[/tex] - Working pressured of the boiler (gauge pressure), measured in pounds per square inch.
If we suppose that [tex]p_{atm} = 14.696\,psi[/tex] and [tex]p_{g} = 10\,psi[/tex], then the absolute pressure is:
[tex]p_{abs} = 14.696\,psi+10\,psi[/tex]
[tex]p_{abs} = 24.696\,psi[/tex]
The corresponding absolute pressure of the boiler is 24.696 pounds per square inch.
The beam below will be subjected to a live load of 600 lb/ft, a concentrated live load of 25 kip, and a dead load of 300 lb/ft. a) What is the maximum positive moment that can be produced at G? b) What is the maximum negative moment that can be produced at G?
Answer:
hello some part of your question is missing below is the complete question
answer :
A) 162750 Ib.ft
B) - 64950 Ib.ft
Explanation:
Applying Muller-Breslau's law
we will make assumptions which include assuming an imaginary hinge at G
therefore the height of I.LD for B.M at G = ( 12 * 8 ) / 20 = 4.8
height of I.L.D at C = 2.4 ( calculated )
height of I.L.D at F = 1.5 ( calculated )
A) Determine Maximum positive moment produced at G
[tex]M ^+[/tex] = [ (1/2 * 20 * 4.8 ) ( 600 + 300 ) ] + [ ( 25 * 4.8 * 10^3 ) ] - [ ( 1/2 *2.4*20 ) * 300 ] + [ (1/2 * 1.5 * 10 ) ( 600 + 300 ) ]
= 162750 Ib.ft
B) Determine the maximum negative moment produced at G
[tex]M ^-[/tex] = [ ( 1/2 * 20 * 4.8 ) * 300 ] - [ ( 1/2 * 2.4 * 20 ) ( 600 + 300 ) ] - [ (2.5 * 10^3 * 2.4 ) ] + [ ( 1/2 * 1.5 * 10) * 300 ]
= - 64950 Ib.ft

Consider fully developed flow in a circular pipe with negligible entrance effects. If the length of the pipe is doubled, the head loss will:_________
(a) double,
(b) more than double,
(c) less than double,
(d) reduce by half, or
(e) remain constant.
Fully developed flow in a circular pipe with negligible entrance effects. If the length of the pipe is doubled, the head loss will double.
What is Negligible entrance?The amount of piping head loss is computed by equating the lengths and distances of all fittings to a particular inner pipe diameter. The length of a flow through a conduit before it completely develops is referred to as the entry length in fluid dynamics.
Entrance length is the length of the entry zone, which is the area immediately following the pipe entrance where effects from the inner wall of the pipe disseminate into the flow as an expanding boundary layer.
As the boundary layer completely fills the pipe and the flow characteristics stop changing as the pipe's length rises, the emerging flow becomes fully formed.
Therefore, Fully developed flow in a circular pipe with negligible entrance effects. If the length of the pipe is doubled, the head loss will double.

applying the expression for calculating solidification time
t = B [tex](\frac{V}{A} ) ^n[/tex] --------- ( 1 )
n = 1.5
B = ?
t = 10 minutes
V = [tex]\frac{\pi d^2}{4} H[/tex]
A = [tex]\frac{\pi d^2}{2} + \pi dH[/tex]

b. From your estimates, calculate (in a rate per week) your rate of job finding, f, and your rate of job separation, s. (Hint: If f is the rate of job finding, then the average spell of unemployment is 1/f.)
c. What is the natural rate of unemployment for the population you represent?
Answer:
Following are the solution to this question:
Explanation:
In point a:
This takes me six weeks for both the took ideas that I was searching for but it continued for 3 years (12 weeks) as it's an intern.
In point b:
Finding job:
[tex]\to f = \frac{1}{6} = 0.166[/tex] jobs weekly
Separation of jobs:
[tex]\to \frac{ 1}{12}=0.083[/tex] employment per week.
In point c:
Its natural rate of unemployment is: [tex]\frac{U}{L} = s+(s \times f)[/tex].
The normal level of employment for that community I represent, once we add up from that preceding section, is as follows:
[tex]\to \frac{U}{L} = 0.083+ (0.083\times 0.166) = 0.096[/tex]
If on average, it requires six weeks to find another job or the work lasted 12 weeks, the group's unemployment level is [tex]0.096 \ \%[/tex].
Pure aluminum is poured into a sand mold. The metal level in the pouring basin is 10 in. above the metal level in the mold, and the runner is circular with a 0.4-in. diameter. What are the velocity and rate of the flow of the metal into the mold? Is the flow turbulent or laminar? 10.44 A cylinder with a diameter of 1.5 in. and height of 3 in. solidifies in 3 minutes in a sand casting operation. What is the solidification time if the cylinder height is doubled? What is the time if the diameter is doubled?
Solution :
Given :
Height at which the metal is poured, h = 10 in
Diameter of the runner , d = 0.4 in
Assume viscosity, μ = 0.004 Pa-s
Now considering Bernoulli's equation to find velocity,
As there is no loss in energy, Δ Pressure energy ≅ 0
So,
[tex]$\frac{v^2_1}{2g}+z_1=\frac{v^2_2}{2g}+z_2$[/tex]
Here 1 and 2 represents top and bottom section of the sprue.
[tex]$\frac{v^2_1}{2g}+z_1=\frac{v^2_2}{2g}+z_2 \ \ \ (v_1=0)$[/tex]
[tex]$v_2=\sqrt{2g \Delta z}$[/tex]
Now substituting [tex]$32.20 \ ft/s^2 = 386.4 \ in/s^2$[/tex] for g and 10 in for Δz in velocity equation,
[tex]$v_2=\sqrt{2 \times 386.4 \times 10}$[/tex]
[tex]$v_2= 87.91 \ in\s = 7.32 \ ft/s$[/tex]
Calculating the area of the basin
[tex]$A=\frac{\pi}{4}d^2$[/tex]
Substitute .04 in for d in the above equation
[tex]$A =\frac{\pi}{4} \times (0.4)^2$[/tex]
[tex]$A= 0.1256 \ in^2$[/tex]
Calculating the flow rate
Q = 0.1256 x 87.91
[tex]$ Q= 11 .04 \ in^3/s $[/tex]
Hence the viscosity is [tex]$v_2 = 87.91 \ in/s$[/tex] and the flow rate is [tex]$Q=11.04 \ in^3/s$[/tex]
Calculating the Reynolds number of the flow,
[tex]$Re = \frac{\rho v d}{\mu}$[/tex]
[tex]$Re = \frac{0.097544 \times 87.91 \times 0.40}{5.8 \times 10^{-7}}$[/tex]
[tex]$Re=5.9 \times 10^6$[/tex]
Therefore, the flow is turbulent.
Now considering the solidification time,
[tex]$t=c \times \left(\frac{V}{A}\right)^2$[/tex]
[tex]$t=c \times \left(\frac{\frac{\pi}{4}d^2h}{2\left(\frac{\pi}{4}d^2\right)+ \pi dh}\right)^2$[/tex]
[tex]$t=c\left(\frac{dh}{2d+4h}\right)^2$[/tex]
Substituting 1.5 for d and 3 for h and 3 min for t to calculate the value of c is
[tex]$3=c\left(\frac{1.5 \times 3}{2 \times 1.5 + 4 \times 3} \right)^2$[/tex]
c = 33.33
For case when height is double i.e. h = 6 in
[tex]$t_h = 33.33 \times \left(\frac{1.5 \times 6}{2 \times 1.5 + 4 \times 6} \right)^2$[/tex]
[tex]$t_h= 3.70 \ min$[/tex]
For case when the diameter is doubled i.e. 3 in for d and 3 in for h,
[tex]$t_d = 33.33 \times \left(\frac{3 \times 3}{2 \times 3 + 4 \times 3} \right)^2$[/tex]
[tex]$t_d= 8.3325 \ min$[/tex]

The formation of faults in Earth's crust is an effect. What causes faults to form in the crust? Global Positioning System sensors beds shaking across New York City the movement of tectonic plates landslides across the Midwest
Answer: The movement of tectonic plates
Explanation:
Tectonic plates are the part of the earth's crust that both the ocean and land rest on. These plates are constantly moving as a result of currents in the mantle.
These movements cause stress on the surface which has the effect of fracturing rocks and thereby creating/ forming faults in the earth's crust. Sometimes faults form when these plates move away from each other and sometimes they are formed when they push into each other.

For a RC Low Pass filter, what is the approximate amplitude (as a decimal proportion of input amplitude) at 1/4 the cutoff frequency?
Answer:
Explanation:
RC low Pass Filter is an electronic circuit that comprises of a resistor and capacitor and it functions to permit low-frequency signals depending on the design and reject the high-frequency signals above a given frequency known as the cutoff frequency.
From the diagram attached below:
[tex]V_{in[/tex] = the input signal
[tex]V_o[/tex] = the output signal
Since; [tex]V_o[/tex] is used across the capacitor C,
By using the potential divider equation we have:
[tex]V_o =V_{in} \times \dfrac{X_C}{\sqrt{ R^2+X_C^2} }[/tex]
From above; [tex]X_C[/tex] = capacitive reactance ;
and The total impedance Z is illustrated as [tex]Z = \sqrt{R^2+X_C^2}[/tex]
Thus;
[tex]V_o =V_{in} \times \dfrac{X_C}{Z}[/tex]
Recall that;
[tex]X_C = \dfrac{1}{2 \pi fC}[/tex]
Here; f denotes the frequency of the input signal
Since the cutoff frequency is related to the frequency at which the capacitive reactance and resistance are said to be the same, then:
The Cutoff frequency can be expressed as:
[tex]F_C = \dfrac{1}{2 \pi RC}[/tex]
Also;
the frequency of input signal [tex]f = \dfrac{F_c}{4}[/tex]
[tex]f = \dfrac{1}{8 \pi RC}[/tex]
Hence;
[tex]X_C = \dfrac{1}{2 \pi fC}[/tex]
[tex]X_C = \dfrac{1}{2 \pi \times \dfrac{1}{8 \pi RC} \times C}[/tex]
[tex]X_C = 4R[/tex]
Finally;
From [tex]Z = \sqrt{R^2+X_C^2}[/tex]
[tex]Z = \sqrt{R^2+(4R)^2}[/tex]
[tex]Z = \sqrt{17R^2}[/tex]
Z [tex]\simeq[/tex] 4.12R
As such, the output will be:
[tex]V_o =V_{in} \times \dfrac{X_C}{\sqrt{ R^2+X_C^2} }[/tex]
[tex]V_o =V_{in} \times \dfrac{4R}{4.12R^2} }[/tex]
[tex]V_o =0.97V_{in}[/tex]
So, if we regard [tex]A_{in}[/tex] to be the input amplitude, then [tex]A_{out}[/tex] i.e the output amplitude will also be [tex]A_{out}[/tex] = [tex]0.97 A_{in}[/tex]

Estimate the luminosity of a 3 -solar-mass main-sequence star; of a 9 -solar-mass main-sequence star. Can you easily estimate the luminosity of a 3 -solar-massred giant star?
Answer:
a) 46.76 Lsun
b) 2187 Lsun
c ) You can easily estimate the luminosity of a 3-solar massed giant star because its luminosity is close to the luminosity of the sun
Explanation:
To estimate the luminosity of a celestial body in terms of solar luminosity we use the expression below
= [tex]\frac{L}{Lsun} = (\frac{M}{Msun} )^{3.5}[/tex]
a) Estimate the luminosity of a 3 solar mass main sequence star
= [tex]\frac{L}{Lsun} = (\frac{3M}{Msun} )^{3.5}[/tex]
Hence ; L(luminosity of a 3 solar mass star ) = 46.76 Lsun
b) Estimate the luminosity of a 9-solar-mass main sequence star
= [tex]\frac{L}{Lsun} = (\frac{9M}{Msun} )^{3.5}[/tex]
hence L( luminosity of a 9-solar mass star ) = 2187 Lsun
c ) You can easily estimate the luminosity of a 3-solar massed giant star because its luminosity is close to the luminosity of the sun
A) The luminosity of a 3 -solar-mass main-sequence star is; L = 46.765L_sun
B) The luminosity of a 9 -solar-mass main-sequence star is; L = 2187L_sun
C) Yes, we can easily estimate the luminosity of a 3 -solar-mass main-sequence star.
We want to find luminosity of a solar body which in this case is a main sequence star. The formula in terms of solar luminosity is;
L/L_sun = (M/M_sun)^(3.5)
Where;
L is luminosity of the solar body
L_sun is luminosity of the sun
M is mass of the solar body
M_sun is mass of the sun
A) Thus;
For a 3 -solar-mass main-sequence star;
M = 3M_sun
Therefore;
L/L_sun = (3M_sun/M_sun)^(3.5)
L/L_sun = 3^(3.5)
L/L_sun = 46.765
L = 46.765L_sun
B) For a 9-solar-mass main-sequence star;
L/L_sun = (9M_sun/M_sun)^(3.5)
L/L_sun = 9^(3.5)
L/L_sun = 2187
L = 2187L_sun
C) We can see from answer A above that the luminosity of a 3 solar mass body is 46.765 times of the luminosity of sun. Since it's not so much bigger than the luminosity of sun, then it is easy to estimate.

What is the first step to cutting internal threads on an engine lathe?
Answer:
zero off your workpiece so you can work from a datum, usually the centre of your work on a lathe. change your tool to a drill and drill a hole to a size smaller than your thread diameter, change out your tool for a threaded tap and away you go.
I'm not sure which part they want but I'd say ensure your tool is set to the right height, you have the tool lines up where you want to cut and that you have calculated the speed you need to cut at safety. Drill a hole before you tap though.
If you have a CNC lathe you just set the programme to do the processes and tool change for you.
The first step to cutting internal threads on an engine lathe is to make calculations so that the thread will have proper dimensions.
What is lathe threading?The technique of thread cutting on the lathe results in a helical ridge with a consistent section on the workpiece.
To work from a datum, often the center of your work on a lathe, zero off your workpiece. Use a drill to create a hole that is less in diameter than the thread, then switch to a threaded tap and carry on.
One would advise making sure your tool is adjusted to the appropriate height, that it is lined up where you want to cut, and that you have determined the speed you must cut in order to be safe. Before you tap, drill a hole.
With a CNC lathe, you can simply program the machine to perform the processes and tool changes for you.
Therefore, to do this, make a series of cuts with a threading toolkit that matches the needed thread form.

0 - 15 _______ 300 _____________ 4 x 300 = 1,200
15 - 30 ______ 400 _____________ 4 x 400 = 1,600 Maximum
30 - 45 ______ 250 _____________ 4 x 250 = 1,000
45 - 60 ______ 350 _____________ 4 x 350 = 1,400
Hence, Maximum hourly flow rate is 1,600
Calculate hourly volume
Hourly volume = 300 + 400 + 250 + 350 = 1,300
Now calculate Peak hour factor
Peak hour factor = Hourly volume / maximum hourly flow = 1,300 / 1,600 = 0.8125
In the NiTi system, there are a number of invariant transformations and solid state phases. How many degrees of freedom are there in the two phase regions and at the invariant points?
Answer:
we have zero degree of freedom (F = 0) at the first phase region and one degree of freedom (F = 1) at the second phase region
Explanation:
given the diagram;
C = 2 { Ti and Ni}, N = 1 {Pr is constant}, P = 3 { L and B}
For degree of freedom,
Gibbs phase rule is applied for invariant point (ex.A)
P + F = C + N
3 + F = 2 + 1
F = 3 - 3
F = 0
For the second phase region ( ex.B)
C = 2, N = 1, P = 2
P + F = C + N
2 + F = 2 + 1
F = 3 - 2
F = 1
Therefore we have zero degrees of freedom (F = 0) at the first phase region and one degrees of freedom (F = 1) at the second phase region
