The wheels, axle, and handles of a wheelbarrow weigh w = 56 n. the load chamber and its contents weigh wl = 616 n. the drawing shows these two forces in two different wheelbarrow designs. to support the wheelbarrow in equilibrium, the man’s hands apply a force to the handles that is directed vertically upward. consider a rotational axis at the point where the tire contacts the ground, directed perpendicular to the plane of the paper. find the magnitude of the man’s force for both designs.
