Need help with this question pls help.

Answer:

Please find attached the diagram end result of the truss with the member reaction forces labelled with the amount of forces as required, created with Microsoft Visio

Explanation:

To answer the question, we note that the sum of the forces in the Truss is zero

Therefore, we have, ∑Fₓ = [tex]\Sigma F_y[/tex] = 0 N

The forces on the members CD and AD are therefore as follows;

Horizontal forces;

[tex]F_{CD}[/tex] × cos(45°) - [tex]F_{AD}[/tex] × cos(30.964°) = 100.0 N...(1)

[tex]F_{CD}[/tex] × sin(45°) + [tex]F_{AD}[/tex] × sin(30.964°) = 750.0 N...(2)

Solving the above system of equations using a graphing calculator gives;

[tex]F_{CD}[/tex] ≈ 715.94 N (Tension)

[tex]F_{AD}[/tex] ≈ 473.76 N (Compression)

[tex]F_{Cy}[/tex] + [tex]F_{Ay}[/tex]  = 750.0 N

[tex]F_{Ax}[/tex] = 100.0 N

From ∑M[tex]_c[/tex] = 0, we have;

[tex]F_{Ay}[/tex] × 8 = 750 × 3 + 100 × 3

[tex]F_{Ay}[/tex] = 2550/8 = 318.75 N

∴ [tex]F_{Cy}[/tex]  = 750.0 N - [tex]F_{Ay}[/tex] = 750.0 N - 318.75 N = 431.25 N

Answer:

stop leaving the stove on, turnof ligts, unplug appliances like air fryers when not in use.

Explanation:

hope this helps, these are just some ideas!

The strategies that can be used to reduce your electricity bill are to turn off lights, disconnect appliances like air fryers when not in use, and quit leaving the stove on.

A hundred years or so ago, electricity began to be widely distributed. Humanity made progress through this method. Today, electricity is used in every industry sector and in all other domains.

You may save money, improve your energy security, and lessen the pollution caused by non-renewable energy sources by reducing energy use in your house.

Therefore, the strategies to save electricity are:

Specialized Bicycle Components, Inc., colloquially known as and stylized as SPECIALIZED, is an American company that designs, manufactures and markets bicycles, bicycle components and related products under the brand name "Specialized", as well as the premium and professional oriented "S-works".

The Morgan Hill, California-based company was founded in 1974 by Mike Sinyard.

The company was founded in 1974 by Mike Sinyard, a cycling enthusiast who sold his Volkswagen Bus for $1,500 to fund a cycle tour of Europe, where he bought handlebars and stems made by Cinelli to take back to the US. Sinyard started out importing Italian bike components that were difficult to find in the United States, but the company began to produce its own bike parts by 1976, starting with the Specialized Touring Tire. In 1981, the company introduced its first two bikes, the Sequoia, a sport-touring design and the Allez, a road bike. Specialized also introduced the first major production mountain bike in the world, the Stumpjumper, in 1981. Like the Sequoia and Allez, the Stumpjumper was designed by Tim Neenan and based on an early Tom Ritchey design. Specialized continues to produce bikes under the Stumpjumper name, including both hardtail and full-suspension models. An original Stumpjumper is displayed in the Smithsonian Institution in Washington, D.C. In 1989, Specialized introduced the Epic, the world's second mass-production carbon fibre mountain bike.

Answer:

Normally closed (NC)

Explanation:

Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.

Mathematically, Ohm's law is given by the formula;

[tex] V = IR[/tex]

Where;

V represents voltage measured in voltage.

I represents current measured in amperes.

R represents resistance measured in ohms.

A switch can be defined as an electronic component or device that is typically used to prevent or allow the flow of electric current (electrons) from one point to another in an electrical circuit.

There are two logical forms used for designing a switch and these includes;

I. Normally opened (NO).

II. Normally closed (NC).

A Normally closed (NC) contact allows current to flow when the switch's operator is not activated.

Basically, a Normally closed (NC) contact would always remained closed unless a certain (specific) condition is met. Thus, when the contacts are moved, the circuit becomes open and thus, prevents the flow of electric current in the circuit.
