Joel uses a claw hammer to remove a nail from a wall. he applies a force of 40 newtons on the hammer. the hammer applies a force of 160 newtons on the nail. the mechanical advantage of the hammer is?

Hi!

Mechanical advantage is defined as the ratio of force produced by an object to the force that is applied to it.

In our case, this would be the ratio of the force applied by the claw hammer on the nail to the force Joel applies to the claw hammer, which is

160:40 or 4:1

So the mechanical advantage of the hammer is four.

Hope this helps!
