Lecture
This lecture covers the analysis of plane stress conditions, focusing on stresses on inclined planes and transformation equations. It discusses the equilibrium of wedge-shaped stress elements, stresses on cylindrical pressure vessels, and stress transformation using trigonometry. The instructor explains how to calculate principal stresses, maximum shear stresses, and shear stresses on principal planes. Special cases like uniaxial stress, biaxial stress, and pure shear are also addressed, providing insights into stress analysis in different scenarios.
