A woman of mass m 509 kg sits on the left end of a, Ask an Expert

Academics

A woman of mass m = 50.9 kg sits on the left end of a seesaw-a plank of length L = 3.99 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 = 71.2 kg sit if the system (seesaw plus man and woman) is to be balanced?

(b) Find the normal force exerted by the pivot if the plank has a mass of mpl = 13.4 kg.
