Question 20

Medium

A uniform horizontal beam of length 3.0 m and weight 60 N is supported by a pivot located 1.0 m from its left-hand end. A load of weight 120 N is suspended from the extreme left-hand end of the beam. A vertical downward force $F\,$ is applied to the extreme right-hand end to keep the beam in horizontal equilibrium.

A uniform horizontal beam of length 3.0 m supported by a pivot 1.0 m from the left end, with a 120 N force at the left end and a force F at the right end.

$N15\text{ N}$

$N45\text{ N}$

$N60\text{ N}$
