The wheels, axle, and handles of a wheelbarrow weigh W-69 N. The load chamber and its contents weigh W₁ - 522 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. (a) F-i (b) F-i 0.400 0.700 m 0.200 m W 6.600 m²0.700 m (b)
