Forces and moments are introduced with vector algebra, followed by the application of equilibrium conditions. Free body diagrams (FBDs) are used to analyse trusses, frames and machines, as well as internal member forces (shear force and bending moment diagrams for beams) and friction. Learn and apply Newton's second law (F=ma) and the kinematics of particles executing general plane motion due to external forces. The course topics focus on visualizing mechanical systems in static equilibrium and developing problem solving techniques.
