The slider cranck mechanism is a classical linkage assembly that transforms a rotational motion into a linear one. It can be found in many systems such as pumps, thermal engines, … (...) This application aims to illustrate the kinematics of the mechanism. It replicates a free software that was available on MECAMEDIA but which is not maintained. It also exists a MatLab version. This application gives the mechanism configuration as well as position, velocity and acceleration plots of the slider given the position and velocity of the eccentric. Besides it illustrates some graphical kinematics tools such as trajectories, velocity vectors and equiprojectivity.
