 The mechanism is made of a frame(0), an eccentric (1), a connecting rod (2) and a slider (3) depicted by the following figure:

 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](https://github.com/mahmoudsamhoud/Cranck-Slider-Mechanism-Computational-Dynamics-). 
 
 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.

 The application works with python37 and the required packages are: numpy and matplotlib
 
 To run the application, you might either:
-* double click on `slider-cranck_mechanism_app.py` if you have a python interpreter set with the right version and libraries;
+* double click on `slider-crank_mechanism_app.py` if you have a python interpreter set with the right version and libraries;
 * in a terminal run the following command :
 ```
-python slider-cranck_mechanism_app.py
+python slider-crank_mechanism_app.py
 ```
 
 **Configuration and plots are not automatically updatedwhen settings are changed.
