Answer:
D) Electric power distribution.
Explanation:
As we know that the Faraday's law of electromagnetic induction says that rate of change in magnetic flux linked with a closed conducting loop will induce EMF in the loop.
This induced EMF is used for power production so here when we use it for the production of voltage across conductor.
it is used in AC generator when a coil is rotated at high speed between strong magnetic field of magnets.
This is induced EMF is given by
so here correct answer will be
D) Electric power distribution.

Answer:
Explanation:
Given that:
width b=100mm
depth h=150 mm
length L=2 m =200mm
point load P =500 N
Calculate moment of inertia
Point C is subjected to bending moment
Calculate the bending moment of point C
M = P x 1.5
= 500 x 1.5
= 750 N.m
M = 750 × 10³ N.mm
Calculate bending stress at point C
Calculate the first moment of area below point C
Now calculate shear stress at point C
Calculate the principal stress at point C
Calculate the maximum shear stress at piont C
