-====== Surface Loads ======
-<WRAP half column>
-Surface loads are applied to faces of the components participating in the simulation by connecting to the Loads input on the stress solver component.

-===== Vector Force =====
-<WRAP group>
-<WRAP half column>
-A "Vector Force" load is a surface load applied to a face in a specified direction. An example of this load is pressing on the top of a book to push it across a table.
-A Vector Load requires three inputs:
-  * the geometry of the surfaces where the load is applied
-  * the direction of the force (a vector)
-  * the magnitude of the force

-===== Bearing Force =====
-<WRAP group>
-<WRAP half column>
-A "Bearing Load" is a surface force applied to a (typically) cylindrical face to approximate the effects of a shaft pressing against the side of a hole.  The applied force gets converted to a varying pressure distribution on the portion of the face experiencing compressive pressure.  The pressure distribution is computed automatically to achieve the specified overall bearing force.
-A Bearing Load requires three inputs:
-  * the geometry of the surfaces where the load is applied
-  * the direction of the bearing force (a vector)
-  * the magnitude of the force

-===== Pressure =====
-<WRAP group>
-<WRAP half column>
-A "Pressure" load is a surface load specified in terms of force per unit area. Positive pressures push into the surface, negative pressure pull.
-A Pressure Load requires two inputs:
-  * the geometry of the surfaces where the pressure is applied
-  * the magnitude of the pressure

-===== Hydrostatic =====
-<WRAP group>
-<WRAP half column>
-A "Hydrostatic" load is a spatially varying pressure due to immersion in a liquid.  The pressure at any point depends on the density of the liquid, increasing from a value of zero at the liquid surface to a maximum at the deepest point.  An example of this load is the pressure applied by water to the hull of a floating boat.
-A Hydrostatic load requires three inputs:
-  * the geometry of the surface where the load is applied
-  * the plane of the liquid surface (parallel to XY plane)
-  * the density of the fluid imparting the load

-===== Torque =====
-<WRAP group>
-<WRAP half column>
-A "Torque" load is a surface load that applies a twisting force around an axis. The direction of the torque is determined using the right hand rule: using your right hand, point your thumb in the direction of the axis. A positive torque value applies a torque acting in the direction the fingers of your right hand would wrap around the axis. The torque load is applied among the load faces with a distribution that varies linearly from zero at the axis.
-A Torque load requires three inputs:
-  * the geometry of the surfaces where the load is applied
-  * the axis of the torque (a line segment)
-  * the value of the torque.
