Solving an axially loaded column for support reactions using force method.

Example bearing resistance

Accés obert

10 de set. 2024

Bearing resistance is a type of failure in connections. It occurs on the plate around the bolt. The affected area is a half circle with non-uniform stress. For simplification, we work with the projected rectangular area, assuming a uniform stress distribution. How many of these areas do you see? Which plate fails earlier?

In this hyperstatic problem, we apply Castigliano's method to add 1 more equation and find support reactions.

Cylindrical pressure vessel

Accés obert

10 de set. 2024

Here you can see a cylindrical pressure vessel. If there is internal pressure, P, what is the magnitude of stresses in the walls? In order to find those stresses, we cut the cylinder in longitudinal and transverse directions, draw free body diagrams and write a force balance. Then we derive equations for longitudinal and transverse (Hoop) stresses. Which stress you think is greater? Longitudinal or hoop stresses?
