Mechanics of Beams

This chapter covers the mechanics of beams, discussing how they resist bending and shear under various types of loads. It examines shear force and bending moment diagrams, types of beam supports, and the principles of static determinacy and indeterminacy. The theory of bending is introduced, including key concepts such as the neutral plane and shear stress distribution, along with related mathematical formulations for understanding beam behavior under load.
