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...

Combining loads and stresses is a difficult task. We’ve all learned Mohr’s circle in college, but there was so much information presented. We’ve boiled it down to what you actually need to know...

Now, let’s go into a little more depth with curved beams and calculate the stress on some popular sections. Let's find out which sections are smart for curved beams and which ones to avoid. ...

Many beams behave like curved beams. Curved beams are unique in that they have high stress concentrations and you can easily make them worse if you are not careful. This video gives a brief overview...

Torsion can be a very simple stress to calculate. On a closed section, like a round tube, it has a very simple formula. On an open section, like a lattice boom, it behaves a dramatically different...

If you are not expecting it, transverse shear and creep up on you. I experienced this in my roller coaster, when the roll back preventers were splitting along the center. Find out what you need to...
