The document discusses principles of transmissibility of forces and resultant force systems. It provides an index and overview of resultant of concurrent and non-concurrent force systems, parallel force systems, characteristics of a force, and moments of forces. Specifically, it defines: 1) The resultant of a concurrent force system as the single force that replaces the original system without changing its external effects. 2) Resultant of non-concurrent forces may be a force system comprising a force, couple, or force and couple. 3) Parallel forces as those with lines of action that are parallel and in the same direction.

3. The Principle oF Transmissibility
“A force may be applied at any point on its given line of action
without altering the resultant effects external to the rigid
body on which itacts.”
Wecan slide the force alongits
line of action.
(forcecan beconsidered as sliding
vector)

4. PARALLEL FORCES SYSTEM
 Forces whose line of action are parallel to each
other & all of them act in same direction.

5. FORCE
 An agent which produces or tends to produce ,
destroy or tends to destroy motion of a body is called
force.
 Unit of force is Newton.
 It is a vector quantity.

6. RESULTANT OF CONCURRENT FORCE
SYSTEM
1. Resultant of Concurrent Forces:
The resultant of a concurrent force system can be defined as the
simplest single force which can replace the original system
without changing its external effect on a rigid body.
2. Resultant of Non-Concurrent Forces:
The resultant will not necessarily be a single force but a force
system comprising a force or a couple or a force and a couple.

8. RESULTANT OF FORCE SYSTEM
1. Resultant of Concurrent Forces:
The resultant of a concurrent force system can be defined as the
simplest single force which can replace the original system
without changing its external effect on a rigid body.
 Coplanar Concurrent Force
 Non-Coplanar Concurrent Force
2. Resultant of Non-Concurrent Forces:
The resultant will not necessarily be a single force but a force
system comprising a force or a couple or a force and a couple.
 Coplanar Non-Concurrent Force
 Non-Coplanarand Non-Concurrent Force

10. CONTACT FORCES
 Force produced by direct contact of bodies is
known as contact force.
 It may be of pull type or push type.
