Problem. A Body Constraint ties two nodes together as a rigid body. The force and moment at the base produced by a load at an offset point are tested.
Reference document. Static equilibrium is used.
A load at the offset point produces this moment at the base. is the distance between the master and the slave node.
Numerical model. The distance between the master and the slave node enters the constraint transformation.
Cantilever with a rigidly offset node
Parameters. L = 3 · e = 0.8 · P = 5,000
Closed form. The moment a load applied at the offset point produces at the base
| Quantity | Reference | Computed | Deviation |
|---|---|---|---|
| Base moment | 19,000 | 19,000 | 0% |
