5a) A force of 285 N is exerted on the end of a
wrench in order to apply a torque of 39.4 N·m to a bolt head. The
point of application of the force is 21.5 cm from the center of the
bolt. What angle does the force make with respect to the wrench
handle?
_________degrees
5b) A 30.0-kilogram child sits on a uniform
seesaw of negligible mass; she is 1.60 m from the pivot point (or
fulcrum). How far from the pivot point on the other side will her
23.0-kilogram playmate have to sit for the seesaw to be in
equilibrium?

The two children are balanced on a seesaw of negligible mass (this assumption is made to keep the example simple). The first child is 26.0 kg and sits .160 m to the left of the pivot. The seesaw has a mass of 12 kg. If the second child is 32.0 kg, how far is she from the pivot? What is the supporting force exerted by the pivot?
