Question

A bucket full of water and weighing 200N is supported by two men holding the handle at each side, each pulling sideways at an angle of 30° to the vertical. Find the force in each man's arm.

Answer 1

At the equilibrium

$$mg=2F\cos30^\circ$$

The force in each man's arm

$$F=\frac{mg}{2\cos30^\circ}=\frac{200\:\rm N}{2*\sqrt{3}/2}=115\: \rm N$$
