ENVI 498 Lecture 5: ENVI 498 lecture notes (5)
Force
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
A number of forces acting on a body.
Coplanar Forces
The forces acting on a body lying in the same plane.
Collinear Forces
The coplanar forces having a common line of action.
Concurrent Forces
The system of forces intersecting at a common point.
Parallel Forces
Those forces having parallel lines of action.
Principle of Transmissibility of a Force
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.
Resultant Force
The single force and associated torque obtained by combining a system of forces and torques acting on
a rigid body.
Resultant of Many Forces Formula
R = √∑F²+∑F²
Angle in which Resultant of Many Forces Act Formula

Document Summary
A pull or push, which acting on a body changes or tends to change, the state of rest or uniform motion of the body. A number of forces acting on a body. The forces acting on a body lying in the same plane. The coplanar forces having a common line of action. The system of forces intersecting at a common point. 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. The single force and associated torque obtained by combining a system of forces and torques acting on a rigid body. Angle in which resultant of many forces act formula. A diagrams used to show the relative magnitude and direction of all forces acting upon an object in a given situation. When a force system has a resultant of 0 magnitude.
