**Mechanical Reasoning Formulas**are a must know if you plan on taking a mechanical reasoning test. I have laid out some basic, must know formulas that will help you succeed your next reasoning test.

The first formula we will cover is **volume.**

The formula for volume is as follows:

Volume(V)= Base x Height (h)

V = πr2 x h

The second need to know formula is for those **leverage** questions. I know we have already covered this in another area of the website but for simplicity and easy access I will add it here as well. You can have a look at our lever page here.

The formula for leverage is as follows:

Weight(W) x Distance (D1) = Force (F) x Distance (D2)

W = Weight

D1 = Distance from fulcrum to weight

F= Force required

D2= Distance from fulcrum to force point

Important mechanical formula number three would be the **inclined plane**. The inclined plane is a slanted surface connecting a lower point to an upper point.

The formula for an incline plane is as follows:

Length of inclined plane / Height of inclined plane = mechanical advantage (MA)

It’s also fairly common that you will see a **common screw in your mechanical reasoning test**. Essentially, a screw is a cylinder with an inclined plane wrapped around it. In this instance, you would have to use a different formula.

Effort x Effort Distance (Circumference) = Resistance x Resistance distance (Pitch)

I’m sure you noticed that there are no examples or explanations shown on this page. This is strictly a formulas page. If you need examples, please be sure to sign up for our free eBook and our free sample questions.
