A force multiplier always has:
AEffort arm longer than load arm
BEffort arm shorter than load arm
CEqual arms
DNo fulcrum
Answer & Solution
Correct answer: A. Effort arm longer than load arm
1. M.A. = effort arm / load arm.
2. For M.A. > 1 (force multiplier), the effort arm must be longer than the load arm.
3. Class II levers have load in the middle, so effort arm > load arm.
4. Hence force multiplier needs longer effort arm.
