Static Analysis: Simple Beam

This lecture covers the calculation of reaction forces in a simple beam using the method of virtual trips. It includes examples of single cuts to determine support reactions and the application of the theorem of virtual work. Students are guided through the process of calculating Cy, Ay, B, and Ma forces by making simple cuts and analyzing the resulting structure. The lecture also introduces the concept of instantaneous centers of rotation and the relationship between structural deformations and rigid body movements.
