How every module teaches
Less noise. More understanding. The essentials taught carefully.
Every module follows the same complete learning system: a readiness check that routes you to the right starting point, the core idea with its limits, a fully worked example in professional 8-step format with real figures, a misconception table, a four-level practice ladder with hidden answers, a closed-notes retrieval quiz with a spaced-review plan, an AI-tutor usage guide, a portfolio task, and a clear next-module route.
Course sequence uses an original MechCompass module order: force modeling, vectors, equilibrium, resultants, rigid bodies, structures, internal forces, friction, centroids, inertia, and virtual work.
The complete Statics path
01 | Module
General Principles
Start with the model. Statics begins when a real object becomes a clean force picture.
02 | Module
Force Vectors
A force is not just "how much." It needs direction before it can be useful.
03 | Module
Equilibrium of a Particle
If all forces meet at one point, the particle model is enough.
04 | Module
Force System Resultants
Replace many force effects with one simpler equivalent effect.
05 | Module
Equilibrium of a Rigid Body
Rigid bodies can translate and rotate, so both forces and moments must balance.
06 | Module
Structural Analysis
Trusses, frames, and machines are solved by exposing the forces inside members.
07 | Module
Internal Forces
Cut the structure to see what it carries inside.
08 | Module
Friction
Friction is a reaction that appears only as much as needed, up to its limit.
09 | Module
Center of Gravity and Centroid
Centroids locate where distributed geometry can be balanced or replaced.
10 | Module
Moments of Inertia
Shape matters because material farther from an axis resists bending more.
11 | Module
Virtual Work
Equilibrium can also be checked through imagined motion and work balance.
