Forces are applied on the beam as shown on the figure at right. Find the torque about point P produced by each of the three forces.

Torque about the 15 N force:

Torque about the 20 N force:

Torque about the 5 N force:

Find the net torque about point P.

A fourth force is applied to the beam at a distance of 0.30 m to the right of point P. What must the magnitude and direction of this force be to make the beam in rotational equilibrium? (this is a hard one – but I know you can do it!)
