We now finally come to the infamous Mohr’s circle! It’s something you’ll definitely be using for future Solid Mechanics/Design courses, so pay attention!

Mohr’s circle is basically a tool that maps all possible stress transformations in a circle. Once constructed, you can easily use it to obtain σ_{1}, σ_{2},
τ_{max in-plane}, θ_{p}, θ_{s} or any stress from any angle of transformation.

Here’s how you construct it:

You can also obtain θ_{p}, θ_{s} or stresses based on other θ
(e.g. θ = 30^{o}) from the Mohr’s circle. Let’s look at an example on how we can do this.
