Andrea is building a birdhouse. She hammers a nail in the wrong place and needs to remove it. She uses the back of her claw hammer to hold the nail and pushes the handle to remove the nail, as shown in the diagram.
Andrea is using the hammer as a simple machine to pry the nail out. What is the mechanical advantage of the hammer?
MA = Effort/Load
a. 0.2
b. 5.4
c. 0.4
d. 2.5
The mechanical advantage of a simple machine can be calculated using the formula MA = Effort/Load. In this case, the effort is the force exerted by Andrea on the handle of the hammer, and the load is the force required to remove the nail.
Since the nail is being removed, the load is equal to the force required to pull the nail out. The effort is the force Andrea applies on the handle of the hammer.
Since we do not have values for the force applied by Andrea or the force required to remove the nail, we cannot calculate the exact mechanical advantage.
So the correct answer is: None of the given options.
