by Ron Kurtus (24 June 2016)

Take this Mini-Quiz to check your understanding of the lesson material.



1. What is the speed mechanical advantage when the output speed is 10 times the input?

The input speed must always be greater than the output speed

10

1/10

2. How does MAS compare with MAD?

They are equal

You can't tell, because you don't have any distances mentioned

They are reciprocals

3. What is the difference between the input and output arms in a catapult?

The output arm has a much greater length than the input arm

They must remain the same to ensure stability
