In addition to combining shear and normal stresses with Mohr’s circle, we also need to know how to add stresses from multiple sources. Some stresses add linearly but others add by the square root of the sum of the squares. We need to know when to use each.
Have you ever wondered if there is an ideal location to put your shelf supports? Well, of course not, you're normal. But if we look at it mathematically….. https://youtu.be/U3r1jAM3Wto
There have been several times in my engineering career that I have needed to limit the force a mechanism can produce, but still allow for unpredictable amounts of deflection. This is very useful in...
