Question

in which of the following is the fulcrum located between the load and effort?

a.) second-class lever
b.) first-class lever
c.) all lever classes
d.) third-class lever

Explanation:

Define lever classes by relative component positions

• First-class lever: Fulcrum is located in the middle, between the effort and the load (E-F-L).
• Second-class lever: Load is located in the middle, between the fulcrum and the effort (F-L-E).
• Third-class lever: Effort is located in the middle, between the fulcrum and the load (F-E-L).

Identify the matching class

• The question asks for the lever where the fulcrum is located between the load and the effort.
• This arrangement (E-F-L) corresponds to a First-Class Lever.

Answer:

• a.) Second-Class Lever
• b.) First-Class Lever (Correct answer)
• c.) All Lever Classes
• d.) Third-Class Lever
