Question

A crowbar moves a distance of .35 meter to lift a load .05 meters off the ground.



what is the ideal mechanical advantage of the crowbar?

Answer 1

The ideal mechanical advantage of the crowbar will be 0.7.IMA is also equal to the distance traveled by the load divided by the distance traveled by the effort.

What is ideal mechanical advantage?

The ideal mechanical advantage of a lever is equal to the length of the effort arm divided by the length of the resistance arm.

The ideal mechanical advantage is found as;

$\rm IMA=\frac{0.35}{0.5} \\\\ IMA=0.7$

Hence,the ideal mechanical advantage of the crowbar will be 0.7.
