Couple driveline axes with Coulomb friction

Clutch blocks allow you to transfer rotational motion and torque among spinning components at different speeds and gear ratios. In general, a single set of gears is not sufficient to accomplish this transfer. Control the time, method, and quantity of transferred power by building high-fidelity custom clutch systems that connect clutches to multiple blocks from the Gears library. Determine how heat generation affects the efficiency and temperature of driveline components using thermal variants of clutch blocks.
