Section 1: Levers and Torque

Question 1: Fulcrum

In a lever, the fulcrum is the:

• A. Pivot point
• B. Load only
• C. Effort only
• D. Rope segment

Answer and Explanation

Correct answer: A. Pivot point

The fulcrum is the point where the lever rotates.

A lever usually includes:

fulcrum
load
effort

Question 2: Longer Wrench
