Note that these practice questions cover MA, IMA, input forces and output forces. Also these kinds of questions might be on the actual test and all ansers can be found in the explanations of the input/ output page and the page that shows you how to calculate MA and IMA.
Input and output questions
1. State the difference between input and output forces.
2.What else can you call the input force and the output force?
3.Explain how a pair of scissors apply output force to a piece of paper.
Mechanical Advantage questions
1. What's the difference between MA and IMA?
2. Does friction affect MA or IMA, why or why not?
3.Calculate a) Fout= 500N Fin= 50N
b) Din=64cm Dout= 4cm
4. Calculate the MA of a car jack when a mechanic exerts 200N on the handle and the jack applies 4000N to the car.
Bonus questions:
1. A gardener has to pull a weed out of the garden. She applies 50N to the shovel and the shovel applies 650N to the weed. Find the MA of the shovel.
2. A lumberjack chops a tree with an ax. He applies 80N to the ax and the ax applies 240N to the piece of wood. Find the MA of the ax.
3.(Answer this question only if you want a challenge.) The handle of a garden tap has a radius of 7.0 cm which is connected to a shaft with a radius of 0.84cm. What is the IMA? (need help? look at your textbook at pg. 138)
