quadrilateral linkage remix
[Meta: will add these after I understand the logic of the project better.]
I am studying force and motion of pedaling and saw Okajima's figure documenting pedal forces for a bicycle that Wilson used in the third edition of Bicycle Science (p. 80). The figure seemed to be both art and science. Okajima used linkages to represent the motion. So, I searched Scratch to see whether any users had created linkage projects.
Darth Pickley created an animation that vaguely resembled Okajima's figure. I remixed the project to see whether I could modify and demonstrate the connection between the cases.
