Use the worked example above to help you solve this problem. A woman of mass m = 59.1 kg sits on the left end of a seesawa plank of length L = 4.11 m, pivoted in the middle as shown in the figure.(a) First compute the torques on the seesaw about an axis that passes through the pivot point. Where should a man of mass M = 73.4 kg sit if the system (seesaw plus man and woman) is to be balanced? m (b) Find the normal force exerted by the pivot if the plank has a mass of m_pl = 11.4 kg. N (c) Repeat part (a), but this time compute the torques about an axis through the left end of the plank. m
