Question

The mechanical advantage of a wheel and axle system is:

• A. Less than 1
• B. Greater than 1
• C. Equal to 1
• D. Infinite

Hint:

The mechanical advantage of a wheel and axle is equal to 1 when the radii are the same.

Answer 1

The Correct Option is C

In the case of a simple wheel and axle system, the mechanical advantage (MA) is given by the ratio of the radii of the wheel and the axle. It is typically equal to 1, as both the input and output forces are equal, but the distance over which the forces act may differ. The formula for mechanical advantage in a wheel and axle system is: \[ \text{MA} = \frac{\text{Radius of the wheel}}{\text{Radius of the axle}} \] In a simple case, where the radii are equal, the mechanical advantage is 1.
