Make a longer lever that will require less force.

Answer 1

To improve the efficiency of a lever system that is only 30% efficient, the best option would be:

Use a stiffer lever to reduce energy lost bending the lever.

This choice addresses the issue of energy loss due to deformation of the lever, which can contribute to inefficiencies. Stiffer materials will better maintain their shape under load, reducing energy loss and increasing the overall efficiency of the lever system.
