Answer:
Yes the statement is true.
Explanation:
Power is defined as the rate at which energy is transferred by an object on account of work done.
Mathematically
An object that does work loses it's energy while an object on which work is done gains energy.
Power is often dependent on the type of energy transfer thus we have Electrical Power, Mechanical Power depending on the type of energy involved in the system.
Concept of power is important since it gives us a measure of how fast energy can be derived to given to a system.

3. The maximum deflection of the beam is 2.55552 inches
Explanation:
1. The height of the beam having a rectangular cross section is h = 2.5 in.
The breadth of the beam, is = 5.5 in.
The moment of inertia of a rectangular beam through its centroid is given as follows;
= b·h³/12 = 5.5 × 2.5³/12 = 1375/192 = 7.161458
= 7.161458
in.⁴
= h·b³/12 = 2.5 × 5.5³/12 = 6655/192 = 36.661458
= 36.661458
in.⁴
The moment of inertia about the base is given as follows;
Iₓ = b·h³/3 = 5.5 × 2.5³/3 = 625/24 = 28.6458
Iₓ = 28.6458 in.⁴
= h·b³/3 = 2.5 × 5.5³/3 = 6655/48= 138.6548
= 138.6548
in.⁴
2. The height of the beam having a rectangular cross section is h = 7 in.
The breadth of the beam, b = 4 in.
The moment of inertia of a rectangular beam through its centroid is given as follows;
= b·h³/12 = 4 × 7³/12 = 114.
= 114.
in.⁴
= h·b³/12 = 7 × 4³/12 = 37.
= 37.
in.⁴
The moment of inertia about the base is given as follows;
Iₓ = b·h³/3 = 4 × 7³/3 = 457.
Iₓ = 457. in.⁴
= h·b³/3 = 2.5 × 5.5³/3 = 149.
= 149.

3. The deflection, , of a simply supported beam having a point load at the center is given as follows;
The given parameters of the beam are;
The length of the beam, L = 22 ft. = 264 in.
The applied load at the center, W = 750 lbs
The modulus of elasticity for Cedar = 10,000,000 psi
The height of the wood, h = 3 in.
The breadth of the wood, b = 5 in.
The moment of inertia of the wood, = b·h³/12 = 5 × 3³/12 = 11.25 in.⁴
By plugging in the given values, we have;
The maximum deflection of the beam, = 2.55552 inches
Answer:n=0.973
Explanation:
Given
When True strain
at
When True stress=346.2 MPa
true strain =0.226
We know
where =True stress
=true strain
n=strain hardening exponent
k=constant
Substituting value
Divide 1 & 2 to get
Taking Log both side
n=0.973
