Question

How could you increase the force advantage of a lever?Select one:a. Make the effort length longer.b. Make the effort length shorter.c. Make the lifting length longer.d. Make the effort force larger.

Answer 1

The ideal mechanical advantage of a lever (IMA) is given by:

$IMA=\frac{Le}{Lr}$

Where:

Le = Effort of the arm

Lr = Resistance arm.

Therefore, we can increase the force adventage by increasing the effort arm or reducing the load arm

Answer:

a. Make the effort length longer.
