Equilibrium of Concurrent Forces A body in which the distance between the constituent particles remains constant under the action of external forces is called a rigid body. When a number of forces or torques act on a body and if the body is at rest or its centre of mass moves with uniform speed the body is said to be in equilibrium.

Algebraic Resolution of a Non-Concurrent System. Given: the system of forces Determine: the resultant by an algebraic method (first its magnitude, and then the point on its line of action where it meets the crooked arm) Solution: The first step is to determine a convenient location for the center of moments. This point should be chosen with care since it can make the problem much easier if
Since the forces acting on a particle always form a concurrent system, the equilibrium of forces gives the necessary and sufficient condition for equilibrium of the system. When we say a particle is in equilibrium, we mean that all the forces acting on it are in balance or that the resultant force is zero.

So for concurrent forces in equilibrium, the forces should all add up to give zero. If a body is not accelerating is in equilibrium , so resultant of all forces = 0. A typical concurrent force …
In a concurrent force system, all forces pass through a common point. In the previous case involving the application of two forces to a body, it was necessary for them to be colinear, opposite in direction, and equal in magnitude for the body to be in equilibrium. If three forces are applied to a body, as shown in the figure, they must pass through a common point (O), or else the condition, SM
EQUILIBRIUM OF NON-CONCURRENT COPLANAR FORCES The figure shows a general coplanar force system.

For the body to be in equilibrium, both linear displacement due to R, and the rotation due to couple M should be …

Static Equilibrium Force and Moment or resultant forces — or at least, not at first sight. The latter concepts are abstractions which you must learn to identify in the world around you in order to work effectively as an engineer, e.g., in order to design an elevator. The problems that appear in engineering text books are a kind of middle ground between abstract theory and everyday

The concept of concurrent and non-concurrent forces are used to study the effect of various forces on an object and whether or not an object would be in a state of equilibrium when a specific set forces is applied on that object.
Solution: The first step is to determine a convenient location for the center of moments. This point should be chosen with care since it can make the problem much easier if correctly chosen.
Since the three forces are keeping the bar in the equilibrium position hence they must be concurrent which means that they must meet at a common point. Hence we can infer that the reaction R will act along AD and the point D will be the point of the concurrency.
coplanar non-parallel forces will always be concurrent. Equilibrium of a particle When the resultant of all forces acting on a particle is zero, the particle is in equilibrium, i.e. it is not disturbed from its existing state of rest (or uniform movement). The closed triangle or polygon is a graphical expression of the equilibrium of a particle. The equilibrium of a particle to which a single

Chapter 3: Rigid Bodies; Equivalent Systems of forces • Rigid Bodies: Bodies in which the relative position of any two points does not change. In real life no body is perfectly rigid. We can approximate the behavior of most structures with rigid bodies because the deformations are usually small and negligible. Even in cases when the deformations are not negligible, we can still apply the

A concurrent coplanar force system is a system of two or more forces whose lines of action ALL intersect at a common point. However, all of the individual vectors might not acutally be in contact with the common point. These are the most simple force systems to resolve with any one of many graphical or algebraic options.
