Question

A uniform rod of length `L` and weight `W` is suspended horizontally by two vertical ropes as shown. The first rope is attached to the left end of the rod while the second is attached to the left end of the rod while the second rope is attached a distance `L//4` from the right end. The tension in the second rope is.
.
A. `(W)/(2)`
B. `(W)/(4)`
C. `(W)/(3)`
D. `(2W)/(3)`

Answer 1

Correct Answer - D
`T_(1) + T_(2) = W`
Taking moment about `A.[C.W. oplus)`
`W xx (L)/(2) -T_(2) xx (3L)/(4) = 0`
`T_(2) = (2W)/(3)`.
