1. Explain the difference between energy and power (2)
Explanation:
Energy is what makes change happen and can be transferred form one object to another. Energy can also be transformed from one form to another. Power is the rate at which energy is transferred. It is not energy but is often confused with energy.
Answer:
• Energy is the ability to do work, and it can be transferred from one body (or system) to another, but is always conserved.
• Power is the amount of energy transferred per unit time.

A cutting tool wears out with a time to failure that is normally distributed with a mean of 10 working days and a standard deviation of 2.5 days. (a) determine its design life for a reliability of 0.99. (b) find the reliability if the tool is replaced every day; every two days; every five days. (c) determine the probability that the cutting tool will last one more day given it has been in use for 5 days.
Using the normalized distribution it is possible to calculate the value of Z score and for cases where there is a 99% chance, so Zscore is -3.6 and X= 16.45.
What are the types of probability distribution?This curve determines the probability of the event associated with it occurring. The Gaussian distribution is the most common, hence it is known as the Normal Distribution. The area under the distribution curve is always equal to 1.0.
The formula for this distribution can be described as:
[tex]Z score = \frac{x-\mu}{\sigma}[/tex]
Where:
x= Probability density functionμ= Meanσ= Standard DeviationIn this case,
[tex]Z score =\frac{1-10}{2.5} \\Z score = -3.6[/tex]
P-value from Z-Table will be P(x<1) = 0.00015911
For 99% we have that z will be 2.58, so
[tex]2.58=\frac{x-10}{2.5}\\x = 16.45[/tex]

Explanation:
Automotive Engineering is one of the most challenging and comprehensive fields of engineering today. The automotive sector has come a long way since the age of steam powered flat engines to the age of fast racing Formula 1 car, light and heavy commercial vehicles with lots of technological developments being done every day. “A good scientist is a person with original ideas. A good engineer is a person who makes a design that works with as few original ideas as possible”.
Engineering has been my passion from the start. I took the first step to become an engineer by securing 93.2% in SSC and 82.8% in HSC. I also secured 8259th rank among 10 lakhs students in AIEEE and 6979th rank among 4.7 lakhs in JEE in 2010 so that I could get a seat in one…show more content…
Additionally, Germany avails the advantages of securing the best of knowledge, quality of education, and above all the international exposure. The quality of German Mechanical Engineering has always been much vaunted. The research carried out on structural design of vehicles, alternative and electrified vehicle propulsion at the University is appealing. The breadth and depth of the courses coupled with a stimulating research environment seem to me the right mix for seminal work and pioneering research. I believe that with variety of courses offered and with highly knowledgeable faculty and excellent facilities, the University will provide a perfect environment to focus all my resources towards my goal.
In summary, I am fully committed to a career in automotive sector. My long term goal is to pursue my research interests in the field of automobiles and strive to emerge as an active contributor to the field in the World in general and India in particular. Hence I am eagerly looking forward to spending the next few years in a structured Master’s program in Automotive Engineering.

A group of friends that are identical in every manner would prevent opportunities for personal development and learning, but having friends with similar interests and values might foster a feeling of community and shared experiences.
Thus, Lack of diversity would limit opportunities for new viewpoints, original ideas, and varied experiences. There might not be enough intellectual and emotional stimulation and repetitious conversations and exchanges.
Because everyone would address problems and obstacles in the same way, life might become predictable and static.
Although conflicts and disagreements may be less frequent, the lack of diverse opinions may make it more difficult to come up with original solutions.

A motor car shaft consists of a steel tube 30 mm internal diameter and 4 mm thick. The engine develops 10 kW at 2000 r.p.m. Find the maximum shear stress in the tube when the power is transmitted through a 4: 1 gearing.
The maximum shear stress in the tube when the power is transmitted through a 4: 1 gearing is 28.98 MPa.
What is power?Power is the energy transferred per unit time.
Torque is find out by
P = 2πNT/60
10000 = 2π x 2000 x T / 60
T =47.74 N.m
The gear ratio Ne / Ns =4/1
Ns =2000/4 = 500
Ts =Ps x 60/(2π x 500)
Ts =190.96 N.m
Maximum shear stress τ = 16/π x (T / (d₀⁴ - d₁⁴))
τ max =T/J x D/2
where d₁ = 30mm = 0.03 m
d₀ = 30 +(2x 4) = 38mm =0.038 m
Substitute the values into the equation, we get
τ max = 16 x 190.96 x 0.038 /π x (0.038⁴ - 0.03⁴)
τ max = 28.98 MPa.
Thus, the maximum shear stress in the tube is 28.98 MPa.

Tech B says that in a four-stroke engine, the piston travels to TDC four times to complete the cycle. Tech B says that in a four-stroke engine, the air-fuel mixture is ignited once every two strokes. Who is correct
Tech B is correct: In a four-stroke engine, the piston reaches TDC twice per cycle, and the air-fuel mixture is ignited once every two strokes.
In a four-stroke engine, the piston travels to Top Dead Center (TDC) two times to complete the entire cycle.
During the first stroke (intake), the air-fuel mixture is drawn into the cylinder, and during the fourth stroke (power), the ignited air-fuel mixture produces power and the piston again reaches TDC.
This means that the piston reaches TDC twice during one complete cycle.
Additionally, Tech B is also correct in stating that the air-fuel mixture is ignited once every two strokes.
The ignition happens during the power stroke (fourth stroke) after the compression stroke (third stroke).
Hence, tech B is correct.
