Description

This lecture covers systems of forces in 2D and 3D, including moments, couples, and the principle of moments. It also delves into rectangular components of vectors, moments about points and axes, and stress and strain in 2D elasticity. The lecture progresses to discuss space trusses, equilibrium in 2D and 3D, frames, machines, distributed forces, beam bending, and virtual work. Additionally, it explores the concept of torque, Varignon's theorem, and the effect of force-couple systems. The lecture concludes with examples illustrating the application of these concepts in real-world scenarios.
