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
Answer
Explanation:
Step1: Recall mechanical - advantage formula
The formula for mechanical advantage (MA) is $MA=\frac{F_{out}}{F_{in}}$, where $F_{out}$ is the output force and $F_{in}$ is the input force.
Step2: Identify input and output forces
The input force $F_{in} = 40$ N (force applied on the hammer) and the output force $F_{out}=160$ N (force applied by the hammer on the nail).
Step3: Calculate mechanical advantage
$MA=\frac{160}{40}=4$
