-====== Body Loads ======
-<WRAP group>
-<WRAP half column>
-Body loads comprise forces that are distributed over a solid volume.  Probably the most familiar of these is the gravitational force acting on a mass to give it weight.
-Body loads are applied by connecting to the volumetric loads input on the Scan&Solve stress solver component.  When several body loads are applied simultaneously, the simulation sums their contributions.

-=====Gravitational Loads=====
-<WRAP group>
-<WRAP half column>
-Gravitational loads simulate the structural effects of a body's self-weight.  For gravitational loads, "up" from the center of the Earth is the +Z direction.
-The gravitational load requires no input, the magnitude is determined by the [[unit system]] in use in Rhino.

-=====Rotational Body Loads=====
-<WRAP group>
-<WRAP half column>
-Rotational body loads simulate the effect of a body rotating around an axis.  Two contributions are considered in a rotational body load: angular velocity, angular acceleration.  The angular velocity term (in radians/sec) simulates the centrifugal effects that tend to throw a body's material away from the axis of rotation.  The angular acceleration term (in radians/sec^2) simulates the effect of a rotational acceleration field around the axis of rotation.  A positive angular acceleration tends to drag the body's material in the positive rotational direction according to the right-hand rule.
-A rotational body load requires 3 inputs:
-  * angular velocity
-  * angular acceleration
-  * axis of rotation

-=====Linear Acceleration Body Loads=====
-<WRAP group>
-<WRAP half column>
-Linear acceleration loads are specified by entering the components of a linear acceleration vector field in which the body is immersed.  The material in the body will tend to be pulled in the direction of the acceleration vector.
-The inputs to the acceleration field are:
-  * the direction of the acceleration field (a vector)
-  * the magnitude of acceleration in units of length/s²
