An experimental device imparts a force of magnitude f = 37 lb to the front edge of the rim at a to simulate the effect of a slam dunk. compute the moment of the force f about point o and about point b. the moments are positive if counterclockwise, negative if clockwise. finally, locate a point c from the base at o to the location on the ground where the force imparts zero moment. the distance d from point o to point c is positive if c is to the right of o, and negative if to the left.
