Mechanical advantage of a machine is the ratio of:
ASpeed to time
BEffort to load
CLoad to effort
DForce to mass
Answer & Solution
Correct answer: C. Load to effort
1. Mechanical advantage (M.A.) tells how much load can be lifted per unit effort.
2. By definition M.A. = load / effort.
3. So the right ratio is load over effort.
4. Larger M.A. means smaller effort needed.
