Forces and Moments
A reviewed 8867 repair guide for Forces and Moments.
Before you begin
Use the diagnostic first. Complete the assigned explanation, worked transfer, guided practice and independent practice in order before the assessment and delayed re-test.
How the ideas connect
- Field, contact and elastic forces
- Moments, couples and centre of gravity
- Translational and rotational equilibrium
Learn in order
Lesson route
Objective clusters
- 01Field, contact and elastic forcesIdentify the interaction and direction independently of velocity; apply Hooke’s law only within its proportional range.
- 02Moments, couples and centre of gravityUse the perpendicular distance to the force’s line of action; a couple has zero resultant force but a non-zero torque.
- 03Translational and rotational equilibriumEquilibrium requires both zero resultant force and zero resultant torque, represented with a complete free-body model.

Course coverage and review details
Restricted to 8867 topic 2(a)–(i), PDF page 11; H2-only depth and omitted H2 topics do not contribute to this profile.
Recorded selected-response work supports formative repair. It does not by itself prove constructed, diagrammatic or practical performance.
