Levers Worksheet: What Type of Lever is it? - Simple Machines | TPT - Free Printable

To solve the problem of identifying the types of levers in the given images, we need to understand the three classes of levers:

Classes of Levers:

1. Class 1 Lever:
- The fulcrum is located between the effort (force applied) and the load (resistance).
- Examples: Seesaw, crowbar, scissors.

2. Class 2 Lever:
- The load is located between the fulcrum and the effort.
- Examples: Wheelbarrow, bottle opener, nutcracker.

3. Class 3 Lever:
- The effort is located between the fulcrum and the load.
- Examples: Fishing rod, tweezers, human arm.
