into the mud. You and
the person driving the
Vehicle want to lift the
truck using a branch.
You apply a force of
600 N to the branch
which acts as a lever.
The rear of the truck
weighs 2,400 N. What
is the mechanical
gain of the lever arm?​

    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

    So, the mechanical  gain of the lever arm is 4.
