Question

type the correct answer in the box. use numerals instead of words. 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

Explanation:

Step1: Recall mechanical - advantage formula

Mechanical Advantage (MA) = $\frac{\text{Output Force}}{\text{Input Force}}$

Step2: Identify input and output forces

Input force = 40 N, Output force = 160 N

Step3: Calculate mechanical advantage

MA = $\frac{160}{40}=4$

Answer:

4
