The figure below shows a painting hanging from a nail fixed into the wall. The picture is supported by a strong, light string attached to the picture symmetrically at two points along the top of the frame. 0.1 m 420 42 05 m 0.75 m Draw a free-body diagram of the painting. If the tension in the string is 60 N, what is the weight of the painting? A person tries to move the painting to the right by pushing on the bottom left edge with a force of 10 N. What moment does this exert about the nail? What force would the person need to apply to the top left edge instead to exert the same moment?

The wheels, axle, and handles of a wheelbarrow weigh W = 55 N. The load chamber and its contents weigh WL = 623 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.
