Use Calculate Forces to silently calculate Kinetostatic Forces Vectors at each joint in each kinematicallydefined chain.
Calculate Forces also calculates the Application Load or Application Load Torque required from a drive system.
The correct element must be configured as the PowerSource  see Configure Power Source.

FORCE 

Action of its surroundings on a body tending to change its state of rest or motion. 
LINE OF ACTION OF A FORCE 
The line along which the vector representing a given force lies. 
MAGNITUDE OF A FORCE 
Number of units of force obtained by comparing a given force with a standard, taken as unit force. 
ACTIVE [APPLIED] FORCE 
Force capable of producing motion. 
REACTION 
Force arising in a constraint and acting upon a constrained body due to the action of an active force upon that body. 
CENTRIPETAL FORCE 
Force causing the centripetal acceleration of a particle. 
INERTIA FORCE 
Product of the mass of a particle and the negative of its acceleration. Following D'Alembert, the inertia force can be regarded as being in equilibrium with the resultant of the all the forces acting on the particle. 
CENTRIFUGAL FORCE 
Inertia force of a particle moving uniformly along a circular path.. 
CORIOLIS FORCE 
Inertia force equal to the product of the mass of a particle and the negative of its Coriolis component of acceleration. 
GRAVITATIONAL FORCE 
Force equal to the product of the mass of a particle and the Gravitational Acceleration on Earth  taken as 9.806m/s/s. 
The Forces calculated include those that result from these Accelerations, in particular : 

CORIOLIS ACCELERATION 
Component of the absolute acceleration of a point due to its velocity relative to a rotating frame of reference: It equals twice the vector product of the angular velocity of the moving frame of reference and the relative velocity of the given moving point. 
CENTRIPETAL ACCELERATION 
Acceleration of a point towards the center of curvature of its path as it moves along a fixed curve. 
TANGENTIAL ACCELERATION 
Component of acceleration of a point collinear with its velocity. 
NORMAL ACCELERATION 
Component of acceleration of a point normal to its velocity. 
ANGULAR ACCELERATION 
Rate of change of angular velocity with respect to time.
