Statics is where most FE structural and mechanical questions begin: bodies at rest, forces in balance, and the reactions that hold everything together.
Each topic below has video walkthroughs, worked examples, and a quiz that regenerates its numbers every attempt.
Statics Topics
Pick where you want to start
Resultant & Equivalent Forces
Combining force systems into a single resultant, and replacing them with an equivalent force and couple.
Equilibrium of a Rigid Body
Free-body diagrams and the equilibrium equations used to solve for unknown reactions.
Frames & Trusses
Two-force members, pinned joints, and the method of joints and sections.
Centroids & Area Moment of Inertia
Locating centroids of composite shapes and computing second moments of area.
Static Friction
Friction on inclined planes, impending motion, and the coefficient of static friction.
Why This Format Works
Videos That Show the Method
Problems are worked visually and conceptually, so you see why each step follows — not just the final number.
Quizzes That Never Repeat
Every attempt regenerates the values, so you practice the technique instead of remembering an answer. Instant feedback and full solutions on every question.
