One end of a uniform wire of length L and of weight W is attached rigidly to a point in the roof and a weight 
is suspended from its lower end. If S is the area of cross-section of the wire, the stress in the wire at a height 3L/4 from its lower end is
A

Text Solution
Verified by ExpertsThe correct answer is:
C
Total force at height 
from its lower end
= Weight suspended + Weight of 3/4 of the chain
Hence stress
