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

Q: 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

(a) $\frac{W_1}{S}$

(b) $\frac{W_1 + ( W/4 )}{S}$

(c) $\frac{W_1 + ( 3W/4 )}{S}$

(d) $\frac{W_1 + W}{S}$
