Welcome to our mechanical aptitude highlight series. Every week, we post a new free question to help you pass your mechanical aptitude test. We cover levers, maps, pulleys, electrical circuits, gears and tools.I hope you find it useful!

Today we will be covering gears with a belt.

The Problem

You are given the problem below. The question is as follows:

It would be incorrect to say that...

1. If wheel Y is the drive wheel, then wheel X will have an increase in speed
2. Wheel Y will turn in the same direction as wheel X
3. If wheel X is moved closer to wheel Y, then wheel Y will turn faster
4. If wheel X is the drive wheel then wheel Y will have an increase in force

If you would like more examples, you can find them in our free sample questions found here. To find more gear examples in our highlight series, you can find those here.
