Force
2D/3D

• Force[bnum, axis, mag] returns a SysLoad data object that applies a force to body bnum of magnitude mag along the specified axis.
• Force[bnum1, bnum2, ... ] applies the force to body bnum1 and also applies a force in the opposite direction to body bnum2.

• After creation, the SysLoad object is passed to SetLoads to alter the state of the current Mech model.
• The following options can be given:

• Magnitude->Relative causes the magnitude of the applied force to be equal to the specified mag times the length of axis.
• See also: Body, Gravity, Load, Moment.

Further Examples

Load the Modeler3D package and define a simple model.

In[1]:=

Here we apply a force and a moment to the crank and look at the resulting loads applied to each model variable. Because we are using Euler parameters the moment is applied in Euler parameter space.

In[2]:=

Out[3]=

Out[5]=

If we switch to global angular coordinates, then the same force and moment will result in the simplest possible load vector.

In[6]:=

Out[9]=

In local angular coordinates the applied moment must be transformed because it was specified in global coordinates.

In[10]:=

Out[13]=

If we redefine the moment in local coordinates, the resulting load vector again requires no transformation.

In[14]:=
