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...

By itself, bending stress calculations don't take buckling into consideration. If missed, you could have a weak section. Watch to find out how we address how to deal with these...

Sections can be funny things. It is important to note that you can make a section strong but not stiff and stiff but not strong. Let's explore why this is and when it...

Wouldn't it be nice to be able to compare the strength of a square tube with a round tube, or even and I-Beam? There is! https://youtu.be/fO8zjfjGafw
