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.**
A stiffer lever would minimize energy losses due to bending and deforming, thereby making the lever system more efficient overall.
**Use a stiffer lever to reduce energy lost bending the lever.**
A stiffer lever would minimize energy losses due to bending and deforming, thereby making the lever system more efficient overall.
