What equation would you use to calculate the ideal mechanical advantage of a wheel and axle in the input force is applied to the axle?

To calculate the ideal mechanical advantage (IMA) of a wheel and axle when the input force is applied to the axle, you can use the equation: IMA = Radius of the wheel / Radius of the axle. This equation highlights the relationship between the radii of the two components, indicating how much the force is amplified based on their sizes. The larger the wheel radius relative to the axle radius, the greater the mechanical advantage.
