Moment of a force about a point. force × perpendicular distance from the point to the line of action of the force. Couple as a pair of equal and opposite coplanar forces. force × perpendicular distance between the lines of action of the forces. Principle of moments. Centre of mass.
Given any point on an extended body, if there is a force acting on that body that does not travel through that point, then that force will cause a moment about that point. As discussed on the moments page, a moment is a force's tendency to cause rotation.
A moment of force, or torque, is a measure of the tendency of that force to rotate a body about a selected point or axis, called the moment center. This tendency increases with the magnitude of the force, and also with the distance between the line-of-action of the force and the moment center.
In this subsection, we show how to calculate the moment of inertia for several standard types of objects, as well as how to use known moments of inertia to find the moment of inertia for a shifted axis or for a compound object.
17 paź 2024 · Shear/Moment diagrams are graphical representations of the internal shear force and bending moment along the whole beam. This is a graphical representation of the variation of the shearing force on a portion or the entire length of a beam or frame.
