A weight `w` is supported by two strings anclined at `60^(@)` and `30^(@)` to the verticle. The tentions in the strings are `T_(1)` and `T_(2)` as shown. If these tentions in the are to be determined in terms of `W` using a tringle of force, which of these trianles should you draw? (block is in equilibrium)

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
C

`vec(AB)=vecWVEC(BC)=vecT_1vec(CA)=vecT_2`
`vec(AB)=vec(BC)=vec(CA)=0` (as the block is at rest)
