The truck in which
you were seated sank
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?​

Respuesta :

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 :

[tex]m=\dfrac{2400}{600}\\\\m=4[/tex]

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