Question

you use a lever to lift a heavy tree branch. you apply a force of 50 n and the lever lifts the branch with a force of 90 n. what is the mechanical advantage of the lever?

Answer 1

3.5

Step-by-step explanation:

checked on APEX

Answer 2

1.8

Step-by-step explanation:

Mechanical advantage is given by the ratio of the load lifted to the force applied to lift the load

In this case Mechanical advantage=L/E where L is the load and E is the effort applied

Mechanical advantage= 90/50 =1.8
