18. o The wheels, axle, and handles of a wheelbarrow weigh 60.0 N.
The load chamber and its contents weigh 525 N. The drawing shows these
two forces in two different wheelbarrow designs. To support the wheel-
barrow in equilibrium, the man's hands apply a force F 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.
