To improve the efficiency of a lever system that is currently only 30% efficient, the best option among the listed choices is:
• Make a longer lever that will require less force.
A longer lever reduces the amount of force needed to lift a load, making the system more efficient by maximizing the mechanical advantage. The other options may not significantly increase efficiency or may even complicate the system without guaranteeing improved efficiency.
• Make a longer lever that will require less force.
A longer lever reduces the amount of force needed to lift a load, making the system more efficient by maximizing the mechanical advantage. The other options may not significantly increase efficiency or may even complicate the system without guaranteeing improved efficiency.
