alleryMatch each class of levers with the position of its central component:
A1-A, 2-B, 3-C
B1-B, 2-A, 3-C
C1-C, 2-B, 3-A
D1-A, 2-C, 3-B
Answer & Solution
Correct answer: A. 1-A, 2-B, 3-C
Class I has Fulcrum in middle. Class II has Load in middle (MA > 1). Class III has Effort in middle (speed multiplier).
