Course Description

Strengthen the fundamentals that power real machines, structures, and products with this free online Engineering Mechanics course in Professional Skills, focused on Mechanical and Industrial Basics. Whether you are starting mechanical engineering studies or returning to core concepts for work, you will learn how to turn physical situations into clear models, choose correct sign conventions, and reason from principles instead of memorizing disconnected formulas.

The course develops the mindset used in industry to analyze systems reliably: identify forces, determine resultants, and judge when a body is truly in equilibrium. You will practice building accurate free body diagrams, working with common force systems, and applying classic tools such as Lami’s theorem, moments, Varignon’s theorem, and the concept of couples. As you progress, the focus expands from particles to rigid bodies and practical structures, including trusses and frames, helping you understand supports, reactions, and how loads travel through members.

Real engineering decisions often depend on how surfaces interact and how mass is distributed, so you will also work through friction concepts and idealized behavior, then move into centroids, centers of gravity, and moments of inertia. Key theorems like the parallel and perpendicular axis theorems and radius of gyration connect geometry to performance, supporting better design intuition for sections and components.

From there, the course bridges into motion: rectilinear and curvilinear kinematics, tangential and normal components, rotation, and the link between linear and circular motion. You will then connect motion to causes through kinetics, momentum, impact, and collision laws, and consolidate understanding with D’Alembert’s principle, work, power, and energy. Exercises and numericals reinforce each step so you can confidently solve engineering mechanics problems and apply the same approach to new scenarios in academics, internships, and everyday mechanical design tasks.
