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.
