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 $$W1$$ 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

Question

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 $$W1$$      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

Force at a height $$3L/4$$ from its lower end                                      $$=$$ Weight  suspended $$+$$ weight of (34)      of the chain                                  $$=$$ $$W1+(3W4)$$                             Stress $$=$$ $$(W1+3W4)/S$$

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 $W_{1}$ 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
