Which action is most likely to increase the ME of the pulley system shown,
and why?
O A. Lengthen the ropes, because this would increase the distance over
which input force can be applied to the pulley.
B. Replace the ropes with thick cables, because this would increase
friction that produces non-useful output work.
C. Shorten the ropes, because this would decrease the distance over
which the pulley can apply output force.
D. Replace the wooden parts with plastic parts, because this would
decrease friction that produces non-useful output work.
