Model Mechanical Systems
                           
                           A mechanical system can be thought of as being composed of a set of basic mechanical         entities that interact with each
                              other by exchanging energy or information in well-defined         ways. For example, a simple pendulum system is composed
                              of a rigid body connected to the         ground by a revolute joint. MotionSolve provides physics-based,         mathematical models of such entities and ways to assemble them into realistic models of 
                              complex mechanical systems. It then lets you simulate your models to gain insight into their         behavior.
