Question

Mechanical Advantage may be calculated using all of the following except ___.

A. counting the number of supporting ropes of a pulley system


B. dividing resistance force by effort force


C. multiplying resistance force by effort force


D. dividing effort distance by resistance distance

Answer 1

The only exception of calculating mechanical advantage is by multiplying resistance force by effort force. For example, in calculating the mechanical advantage of a lever, we consider its output and input forces. The equation would now be as follows:

Mechanical advantage = output force / input force
