Question

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 BLANK

Answer 1

Answer: The mechanical advantage of the hammer is 4.

Step-by-step explanation:

We know that the mechanical advantage of the hammer is is given by the ratio between the force applied on the hammer and the force required to overcome the given force.

Force applied = 40 N

Force required= 160 N

Mechanical advantage =$\frac{\text{force required}}{\text{force applied}}$

Mechanical advantage =$\frac{160}{40}=4$

Hence, the mechanical advantage of the hammer is 4.

Answer 2

Mechanical Advantage = Force by Hammer / Force by Nail = 160/40 = 4
