To improve the efficiency of a lever system that is currently only 30% efficient, you might consider the following options:
1. **Make a longer lever that will require less force**: A longer lever can help reduce the amount of force needed to lift a load, potentially improving efficiency, as you can apply a smaller force to achieve the same load lifting result.
2. **Use it with a lighter load to make it easier**: Reducing the load will directly improve the mechanical advantage realized with the lever, thereby increasing efficiency.
3. **Use a stiffer lever to reduce energy lost bending the lever**: A stiffer lever would minimize energy losses due to bending and deformation, contributing to better overall efficiency.
4. **Have more than one person help to lift the lever**: While more people may apply additional force, it does not inherently improve the efficiency of the lever system itself, as efficiency is a measure of output work versus input work.
Among these options, making a longer lever and using a stiffer lever are more aligned with standard principles of improving the efficiency of lever systems. However, using a lighter load could provide the most immediate improvement in ease of use.
