Torque. , also called . moment. or . moment of force. , is the tendency of a force to rotate an object about an axis, fulcrum, or pivot. Just as a force is a push or a pull, a torque can be thought of as a twist. . Analysis of Annular Plate APPENDIX F Objectives:Create a geometry model of an annular plate.Apply a distributed load of 1.2 lb/in along 10 in from the center of the plate, between the inner and outer The moment produced by two equal, opposite, and . non-collinear . forces is called a . couple. . . M=F(. a+d. )-. Fa. M=. Fd. Its direction is counterclockwise . Vector. We may also express the moment of a couple by using vector . 2. FBD : 3D Force Reaction. 1 unknown. 3 unknown. 2 unknown.

In two-dimensional analyses it is often convenient to determine a moment magnitude by scalar multiplication using the moment-arm rule. In three dimensions, however, the determination of the .
