Question

You use a lever to lift a heavy tree branch. You apply a force of 30 N and the

lever lifts the branch with a force of 120 N. What is the mechanical advantage
of the lever?
A. 4
B. 0.25
C. 2
D. 90

Answer 1

D 90 subtract it

Step-by-step explanation:

Answer 2

If you use a lever to lift a heavy tree branch. The mechanical advantage of the lever is: A. 4.

What is the mechanical advantage?

The mechanical advantage of a lever is the ratio of the output force to the input force.

Input force =30 N

Output force= 120 N

To determine the mechanical advantage divide the output force by the input force:

Mechanical Advantage = Output Force / Input Force

Mechanical Advantage = 120 N / 30 N

Mechanical Advantage = 4

Therefore the mechanical advantage of the lever is: A. 4.
