Study Notes
Force and Equilibrium
- The state of a body under the action of forces is called equilibrium.
Conditions of Equilibrium
- For co-planar concurrent forces, the conditions of equilibrium are that the resultant of the forces must be zero.
- For co-planar non-concurrent forces, the conditions of equilibrium are that the resultant of the forces must be zero and the sum of the clockwise moments about any point is equal to the sum of the anticlockwise moments about the same point.
Uniform Motion
- A particle moving with uniform speed is said to be in uniform motion.
F.B.D.
- F.B.D. stands for Free Body Diagram, used in the context of equilibrium.
