Quantum Mechanics for Scientists &
Engineers – Presentation Viewgraphs – Miller
Statics - answers-a science which deals with the action of forces on bodies, the forces being so
arranged that they are in equilibrium.
Force - answers-a pull or push, which acting on a body changes or tends to change, the state of
rest or uniform motion of the body. Measured in Newton (N).
Force System - answers-a number of forces acting on a body.
Coplanar Forces - answers-the forces acting on a body lying in the same plane.
Collinear Forces - answers-the coplanar forces having a common line of action.
Concurrent Forces - answers-the system of forces intersecting at a common point.
Parallel Forces - answers-those forces having parallel lines of action.
Principle of Transmissibility of a Force - answers-states that if a force acts at any point of a rigid
body it may be considered to act at any other point in its line of action provided the point is
rigidly connected with the body.
Parallelogram Law of Forces - answers-states that if two forces acting at a point be represented
in magnitude and direction by the adjacent sides of a parallelogram, their resultant is
represented in magnitude and direction by the diagonal of the parallelogram passing through
