Support reactions can resist forces and moments, depending upon the type of support. For 2D and 3D supports: If a support prevents the translation of a body in a given direction, then a force is developed on the body in that direction If a support prevents the rotation of a body in a given direction, then a couple moment is exerted on the body Support Reactions you must know: Support Diagram Support Reaction Roller Pin Fixed
