Numerical solutions to inverse problems of general planar motion

In this paper motion as a combination of translation of the base point O and rotation about axis Z of a plane mechanism. The equations of the fixed centrode (B), the trajectory (T) and the movable centrode (R) are obtained. Three inverse problems are studied: if two of these curves are known, find the third one. Implicit differential equations are obtained. Numerical methods to solve these implicit differential equations are presented.
