Question

Which mathematical formula would you use to calculate the IMA of a wheel?

Answer 1

W = F x D

The work you put into a machine -- the input force -- is the force you apply times the distance you apply it. The work done by the machine equals the resisting weight times the distance it moves when you perform the work.

Answer 2

Answer: $IMA = \dfrac{R}{r}$

Explanation: In generally IMA is the ratio of the resistance force and the effort force.

IMA for wheel:

Ideal Mechanical Advantage is the ratio of the radius of the wheel and radius of the axle.

The formula of IMA of a wheel is

$IMA = \dfrac{R}{r}$

Where, R is the radius of the wheel and r is the radius of the axle.
