How Dual Disc Clutches Work and defy basic physics Why do dual disc clutches hold more torque? (Part 2) So here's the trick. Since the discs are stacked versus a single surface, each disc gets the full 1,000 pounds across its 10 square inches of surface or now the equivalent of 2,000 pounds of force acting on 20 square inches which gives us the same exact pressure or 100 pounds per square inch on each friction surface. Still sounds funny right? doubling the **force (misspoke here, sorry!) and the surface area still gives us the same pressure. Let's go back to the sliding block example. Since the discs are stacked and each one has the full 1,000 pounds acting on it, it's like having two blocks now equaling twice the weight- or N in the equation with the same friction coefficient u- which finally doubles the F or force in the equation. So by stacking the discs, allowing the full pressure of the pressure plate to act on each disc and not be divided by them, we're finally able to double the core capacity of the system by adding more discs. . .

How Dual Disc Clutches Work and defy basic physics Why do dual disc clutches hold more torque? (Part 1) So the reason why F=uN doesn't seem to work is we're doubling the surface area which typically reduces the pressure on any given square inch of the friction surface. Let's say you put 1,000 pounds of force on 10 square inches of disc- each square inch would now have 1,000 pounds per 10 inches squared or 100 pounds per square inch of pressure acting on it. Now let's double the surface area and try this again. We have 1,000 pounds of force again but this time 20 square inches of disc; so now we have 1,000 pounds for 20 inches squared or 50 pounds per square inch of pressure. Huh... that just went the wrong way. Well doubling the surface area with half the pressure on each given area ends up cancelling each other out and we end up with the same holding capacity- but that would only be if we are doubling the surface area of a single disc or a block sliding across the floor like we did back in physics class. . .
