An i ntroduction to moments and mechanical forces of rotation. Forces can cause an object to rotate and the turning effect of the force is called a moment. If a resultant force acts on an object about a fixed turning point (the pivot) it will cause the object to rotate e.g. turning a nut with a spanner, applying a screwdriver, opening a door fixed on hinges.

Explanation: The couple is the cross product of the force and the perpendicular distance between the forces. And if the division of the both is done than the resulting quantity is the distance only. But care must be taken that the product is the cross product and hence sine angle must be divided too to get the distance.

Jan 09, 1998 · Moment: The resultant of a system of forces causing rotation without translation. A moment can be expressed as a couple. Moment of inertia: Moment of inertia has two distinct but related meanings: 1) it is a property of a an object relating to the magnitude of the moment required to rotate the object and overcome its inertia. 2) A property of a ... The compression stresses can be represented by a compression force (stress resultant) while the tensile stresses can be replaced by an equivalent tensile force. (1) As a result of the external loading on the structure and the deflection that this induces, we end up with two forces acting on the cut cross-section. A system of forces may be represented by a resultant force which has the same effect as the system. The resultant force, much like any other force, has magnitude and direction. The geometric sum of the forces will yield the resultant.
