The wheels, axle, and handles of a wheelbarrow weigh W= 62 N. The load chamber and its contents weigh WL = 665 N. The drawing shows these two forces in two dissimilar 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. Discover the magnitude of the man’s force for both designs.
