Hi folks! I was wondering if anyone can help me with a problem I'm having with the concept of thermocouples. If I understand correctly, there should necessarily exist a temperature GRADIENT in one of the conductive couples in order for the emf to be generated. So how can you make sure...

The more the merrier! Actually, my design so far is based on a CVT with a ratio varying from 1/3 to 3, but I don't know if this is practical or not, and I can still use a range wider than that.

Hi! I'm designing a human powered vehicle and I need to use a CVT (Continuously variable transmission) in its drive line. I want to know the widest range that the speed ratio of a normal CVT (One that's not very big, heavy, or expensive because our vehicle needs to be as light and cheap as...

Thanks a lot you both! Doc Al: This is exactly what I need, but the link you provided is just the theory. I need actual formulations, whether numerical or analytical. For example, a function for the force distribution on the contact patch (as in the 3rd diagram of the link) could prove to be...

Hey guys! I'm doing my B.S thesis (Mech. Eng.) and I've come across the problem of a rolling disk with friction. Imagine a disk in real world rolling on a flat surface with no external force or torque applied to it except for the interaction of the surface (Normal, friction, etc.). Now...
