Calculating Mechanical Advantage and Efficiency of Simple Machines. In general, the IMA = the resistance force, Fr, divided by the effort force, Fe. IMA also equals the distance over which the effort is applied, de, divided by the distance the load travels, dr. What is the IMA of an inclined plane? ima of a lever.

How is mechanical advantage calculated?

To determine its mechanical advantage you’ll divide the length of the sloped side by the width of the wedge. For example, if the slope is 3 centimeters and the width is 1.5 centimeters, then the mechanical advantage is 2, or 3 centimeters divided by 1.5 centimeters.

How do you find the IMA of a wheel and axle?

As shown in the figure, the ideal mechanical advantage is calculated by dividing the radius of the wheel by the radius of the axle. Any crank-operated device is an example of a wheel and axle.
