Kinematics 89-1 Introduction to plane motion of a rigid body In engineering, we often encounter the plane motion of a rigid body which is more complicated. Investigation into this kind of motion is conducted on the basis of translation and rotation of a rigid body using composition and decomposition of motions. Decomposing a plane motion into translation and rotation, and employing the theory of composition of motions the formulae for finding the velocity and acceleration of point in the rigid body can be derived 1. Definition of plane motion of a rigid body The distance between any point in a rigid body and a fixed plane al ways keeps unchanged during its motion. In other words, any point in the rigid body moves in a plane parallel to the fixed plane The motion described above is called plane motion of a rigid body
