Free online course Statics course

About the free online course

Strengthen your engineering and physics foundations by learning how forces really behave when nothing is accelerating. This free online statics course is designed to help you move from memorizing formulas to thinking like a problem solver, so you can set up clean models, choose the right equations, and finish problems with confidence.

You’ll start with the essentials that make or break performance in statics: Newton’s laws, scalars and vectors, and the language of vector addition. From there, you’ll build the skill of expressing forces in different forms, switching between component notation and geometric approaches, and handling non-orthogonal axes without getting lost. As the course progresses, you’ll extend those ideas into three dimensions, using tools such as directional cosines, unit vectors, coordinates, and the dot product to connect geometry with calculation.

With that vector toolbox in place, you’ll work through equilibrium of particles in 2D and 3D, learning how to write clear force-balance equations and how to approach multi-cable, pulley, and spring setups. You’ll then step up to rigid-body mechanics through moments and torque, building intuition for r×F, moments about a point, about an axis, and the special behavior of couples. Along the way, you’ll develop the habit that top students rely on: translating messy real situations into a consistent diagram and a reliable set of unknowns.

The course also connects statics to the problems you see most in exams and real applications: simplifying force systems into equivalent systems, finding reactions at supports in both 2D and 3D, and checking overall system equilibrium. You’ll gain a practical understanding of centroids and distributed loads, and then apply statics methods to structures through trusses, frames, and machines. As you advance, you’ll practice internal forces in members, build shear and moment diagrams with different solution styles, and tackle friction scenarios that require careful reasoning about impending motion.

To keep you progressing, the course includes targeted exercises and review-focused practice that reinforce setup, sign conventions, and efficient solving strategies. By the end, you’ll be better prepared for school assessments and for next-step subjects that depend on statics, with a clearer, more dependable approach to engineering problem solving.
