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. . .

How Dual Disc Clutches Work and defy basic physics What are the advantages of dual disc clutches? The main advantage of a dual disc clutch is that it can handle more torque than a single disc clutch because the two discs provide twice the surface area for friction which allows them to dissipate heat more effectively. Hmm... well, kind of. Doubling the surface area does allow twice the surface area to reject the heat and it does provide twice the surface area for wear so you get longer life out of them versus an equivalent single disc clutch. Dual disc clutches are also less likely to slip than single disc clutches which makes them ideal for high performance application which makes them ideal for high performance application. Yes that's true as well and actually the whole point of going to a dual disc clutch versus a single, but still not answering why they hold more torque when the basic physics equation isn't making sense yet. . .
