Question

Calculate the ideal mechanical advantage of a lever where the effort arm is 75 cm and the load arm is 15 cm.

Answer 1

Given Data:

Effort Arm = 75 cm

Load Arm = 15 cm

Calculation:

Mechanical Advantage (M. A.) = `"Effort Arm"/"Load Arm"`

= `75/15`

= 5

The ideal mechanical advantage of the lever is 5 (It has no unit).
