Answer:

m = 4

Explanation:

We have,

You apply a force of 600 N to the branch which acts as a lever. It means it is input force, IF = 600 N

The rear of the truck weighs 2,400 N. It means it is output force, OF = 2400 N

The ratio of output force to the input force is equal to the mechanical advantage of the lever arm. It is given by :

$m=\dfrac{2400}{600}\\\\m=4$
