500lbs pressing down on two gears. Surface area of contact on one gear is 0.03125 inches squared. I calculated pressure. 500lbs / 0.0625 = 8000psi being exerted onto the two gears' surface areas. One gear has 4000psi. The gears' radius is 0.47 inches. I calculated torque for an individual gear. 4000psi (0.47 inches) = 1880 inch pounds. (I think I just found my mistake, but I'll finish posting this with my new results). So the torque being applied to the gears is 1880 inch pounds each. I guess working through the problem for the 3rd time helped. But I would welcome anyone to double check my triple check. I still may have misunderstood something and my calculations are off.
