question:
which type of lever does a wheel and axle become when force is applied to its axle?
possible answers:
first - class
second - class
fourth - class
third - class

Explanation:

A wheel and axle is a modified lever. When force is applied to the axle, the fulcrum is at the center (the axle's axis), the applied force is between the fulcrum and the load (which acts on the wheel's edge). This matches the definition of a third-class lever, where the effort is located between the fulcrum and the resistance/load.

Answer:

Third-class
