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.
O 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.
O D. Replace the wooden parts with plastic parts, because this would
decrease friction that produces non-useful output work.
