Question

A circular roller of weight W hangs by a tie rod and rests against a
smooth vertical wall as shown in fig the tension in the tie rod AB will be​

Answer 1

Answer:

BECAUSE IT IS GRATER THAN W

Answer 2

From the free body diagram of the given figure ,

cos∅ = $\frac{radius\ of \ circular\ roll}{length\ of\ tie\ rod}$

from the observation, ∅<90°, sin∅<1.

Tension in tie rod can be obtained from Lami's theorem:

$\frac{W}{sin(2x)} = \frac{T}{sin90}$               (x = ∅)

Therefore, T >w

Tension in rod is greater than the weight W of circular roller.
