Engineering Mechanics · Course 1 of the core sequence

Statics

Forces, moments, equilibrium, structures, friction, centroids, inertia, and virtual work. Eleven modules, one per textbook chapter, each built to teach, test, and route you.

01

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 an exact chapter mapping.

Course sequence follows R.C. Hibbeler, Engineering Mechanics: Statics, chapters 1 to 11, with recommended Fundamental Problems in every module.

The color code. One convention across every figure and page: red for loads, green for reactions, blue for internal forces, gold for dimensions.

The complete Statics path

01 · Beginner

General Principles

Start with the model. Statics begins when a real object becomes a clean force picture.

Start module →

02 · Beginner

Force Vectors

A force is not just "how much." It needs direction before it can be useful.

Start module →

03 · Beginner

Equilibrium of a Particle

If all forces meet at one point, the particle model is enough.

Start module →

04 · Intermediate

Force System Resultants

Replace many force effects with one simpler equivalent effect.

Start module →

05 · Intermediate

Equilibrium of a Rigid Body

Rigid bodies can translate and rotate, so both forces and moments must balance.

Start module →

06 · Intermediate

Structural Analysis

Trusses, frames, and machines are solved by exposing the forces inside members.

Start module →

07 · Intermediate

Internal Forces

Cut the structure to see what it carries inside.

Start module →

08 · Advanced

Friction

Friction is a reaction that appears only as much as needed, up to its limit.

Start module →

09 · Advanced

Center of Gravity and Centroid

Centroids locate where distributed geometry can be balanced or replaced.

Start module →

10 · Advanced

Moments of Inertia

Shape matters because material farther from an axis resists bending more.

Start module →

11 · Advanced

Virtual Work

Equilibrium can also be checked through imagined motion and work balance.
