Point C is the centre of mass of the rigid body shown in figure. Find the total torque acting on the body about point C.

A

`tau=3.71N-m`

B

`tau=2.71N-m`

C

`tau=8.91N-m`

D

`tau=1.71N-m`

Text Solution

Verified by Experts

`tau_(10N)=0`
`tau_(20N)=(20cos45^(@)xx0.1)` (clockwise)
`=1.414N-m`
`tau_(30N)=(30sin60^(@)xx0.05)` (clockwise)
`=1.299N-m`
`thereforetau_(Total)=2.71N-m`
