Summary
Analytical shortcuts are introduced for calculating the sectional properties of thin-walled beams for stiffness in bending and in torsion. The performance of a simply-supported beam is then introduced in the context of its optimal stiffness, where deflections are minimised relative to the weight of the beam using a dimensional analysis approach.
