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 Sis the area of cross- section of the wire, the stress in the wire at a height (3L/4) from its lower end is:

• A

  ${\mathrm{W}}_1/\mathrm{S}$

• B

  $\left[{\mathrm{W}}_1+(\mathrm{W}/4)\right]\mathrm{S}$

• C

  $\left[{\mathrm{W}}_1+(3\mathrm{W}/4)\right]/\mathrm{S}$

• D

  $\left({\mathrm{W}}_1+\mathrm{W}\right)/\mathrm{S}$
