I am working on Hydraulic brake system in Simulink. I have rotational motion of the pedal and from that I want translation of the following rod. I tried to use Prismatic joint but it doesn't give the motion I need. What should I do?
I believe you need the Wheel and Axle block or the Rack and Pinion block to convert rotational motion to translational motion. ...

Hey guys. I'm doing a project on designing epicyclic gearbox. You are meant to be able to change the ratio and the diameter of the sun gear. The problem is that I can't think of a way to make them always mesh. So any ideas??
You will need to carefully check your radii, gear ratios, initial angles, and number of planets. This can all be related algebr...
