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

Options

A.
B.
C.
D.

Answer

C

Explanation

`vec(AB)=vec(W)` . `vec(BC)=vec(T_(1))` . `vec(CA)=vec(T_(2))`
`vec(AB)+vec(BC)+vec(CA)=0` (as the block is at rest)
