link_solver will solve for any two unknowns in a mechanical linkage system. It is precompiled to solve for systems up to 10 mechanical linkages. If the symbolic library is installed then it can be expanded indefinitely.
Example: Given the four bar linkage in the shape of a square, the top bar length and angle is 'unknown'.
Will correctly identify that the second link is of length 5 with angle 0.
All functions accept matrix input to solve for multiple orientations at once.
Will solve for the angles of links 2 and 3 of a mechanical slider four bar system. As linkage 1 is rotated a full 360 degrees.
draw_bar will take the output from link_solver and create a plot for a given mechanical system. This can be put in a for loop to create a movie of the motion of a mechanical linkage system.
Includes documentation, examples (with published code) and movies of mechanical systems.
(fourbar is just a wrapper for link_solver to solve for four bar linkages.)
