In Fig, the bar is uniform and weighing `500 N`. How large must `W` be if `T_(1)` and `T_(2)` are to be equal?

A

`500N`

B

`300N`

C

`750N`

D

`1500N`

Text Solution

Verified by Experts

The correct Answer is:
D
Taking torque about the attachmet point for `W` get
`-T_(1)(0.4L)+T_(2)(0.3L)+500(0.2L)=0`
`T=1000N`, were `T_(1)=T_(2)=T`
`SigmaF_(y)=0gt2T-W-500=0`
`implies W=1500N`
