Question

A uniform rigid bar of weight W is supported in a horizontal orientation as shown by a rope that makes a 30° angle with the horizontal. The force exerted on the bar at point O, where it is pivoted, is best represented by a vector whose direction is which of the following?

Answer 1

Correct option

   

Since the rope is at an angle it has x and y components of force.

Therefore, H would have to exist to counteract T_x.

Based on Ʈ_net = 0 requirement, V also would have to exist to balance W if we were to chose a pivot point at the right end of the bar.
