As shown in the figure, a uniform plank rests on two supports in equilibrium. The plank's center of mass is at the midpoint of the plank. A block is placed on the left end of the plank. The magnitude of the gravitational acceleration is g = 9.80 m/s2 . L = 6.00 m , D = 4.80 m , mplank = 35.5 kg ,mblock = 6.0 kg. Choose the RIGHT support as rotational axis. It is good practice to mark the rotational axis on the drawing. In the following steps, you will find the magnitude of the two normal forces, N1 and N2.
