Overview
Know and use forces, their resultant forces. Find moment of two or three forces acting at a point Understand the polygon of forces and forces of friction and resolve them
What you'll learn
- Forces in equilibrium
- Resultant of parallel forces (in the same direction and in opposite directions) acting on a rigid body.
- Moment of a force (2 and 3 forces) acting at a point
- Polygon of forces
- Resolution of forces of friction
