 +====== Segment Mass ======
  
 +Every [[visual3d:documentation:modeling:segments:segment_overview|segment]] in a Visual3D model has a mass, which is used to calculate kinetic quantities.
 +
 +=====Default Segment Mass=====
 +
 +The default segment masses defined in Visual3D are based on [[https://deepblue.lib.umich.edu/handle/2027.42/4540|Dempster's regression equations]] and are (relative to total body mass):
 +
 +^ Segment ^ Mass (% body mass) ^
 +|**foot**          |0.0145|
 +|**shank**         |0.0465|
 +|**thigh**         |0.10  |
 +|**hand**          |0.006 |
 +|**forearm**       |0.016 |
 +|**upper arm**     |0.028 |
 +|**pelvis**        |0.142 |
 +|**thorax/abdomen**|0.355 |
 +|**head**          |0.081 |
 +|**trunk**         |0.497 |
 +
 +=====Modifying Segment Mass=====
 +
 +Users can modify Segment Mass under the [[visual3d:documentation:modeling:segments:segment_properties|segment properties]] tab in Visual3D's model builder.
