A horizontal plank 4.00m long and having mass 20.0kg rests on two supports, one at the far left end, and a second 1.00m from the right end. Find the magnitude of the force exerted on the plank by the second pivot. (Hint: If you use the far left end as the point from which you will calculate the torques about it will simplify the problem.) Remember equilibrium conditions mean that sum of torques and forces equals zero.
