Question

what lever has resistance between the axis (fulcrum) and the force (effort)?
a. first
b. second
c. third
d. fourth
please select the best answer from the choices provided.

Explanation:

To determine the lever type, recall the classes of levers:

• First - class lever: Fulcrum is between effort and resistance (e.g., seesaw).
• Second - class lever: Resistance is between fulcrum and effort (e.g., wheelbarrow, where load/resistance is between the axle/fulcrum and the effort applied at the handles).
• Third - class lever: Effort is between fulcrum and resistance (e.g., tweezers).
• "Fourth - class lever" is not a standard lever class.

Thus, the lever with resistance between fulcrum and effort is a second - class lever.

Answer:

B. second
