which list correctly orders effort (E) , fulcrum (F), and load (L) for each lever class? (1 point)

Answer 1

The three classes of levers are categorized based on the relative positions of the effort (E), fulcrum (F), and load (L). Here’s the correct order for each class:

1. First-Class Lever: F - E - L (Fulcrum is between the effort and load)

   • Example: Seesaw

2. Second-Class Lever: E - F - L (Load is between the effort and fulcrum)

   • Example: Wheelbarrow

3. Third-Class Lever: E - L - F (Effort is between the load and fulcrum)

   • Example: Tweezers

So, the orders are as follows:

• First-Class Lever: F - E - L
• Second-Class Lever: E - F - L
• Third-Class Lever: E - L - F
