output force is applied over a shorter distance, so force may need to be applied to the wedge repeatedly to push it
through the object.
Q: Which wedge in theFigure4.87 do you think would do the same amount of work with less input force?
A: The wedge on the left has a greater mechanical advantage, so it would do the same amount of work with less
input force.
