Mini-Quiz: Ramps are Simple Machines

by Ron Kurtus (28 June 2016)

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

1. What is the purpose of a ramp?

The friction is usually great

There are no handles to hold onto

You are too weak to do the job

2. How does the distance you push the object compare with the height lifted?

You are going downhill

You can power the rollers

Friction is much less using rollers

3. What is a simple way to calculate the mechanical advantage?

Divide sliding coefficient of friction by rolling coefficient

Divide rolling coefficient of friction by sliding coefficient

Divide force mechanical advantage by rolling coefficient

If you got all three correct, you are on your way to becoming a Champion in Understanding Machines. If you had problems, you had better look over the material again.

Keep on rolling in your life
