No human power couldkeep these flying masses ofsteel on the speedway curveif it were level. They would behurled through the barriers todestruction. That gives you an idea of theforce of momentum! When a car turns—against itswill—the pressure toward theoutside of the curve is weight, intensified manytimes, bears sidewise on thewheels, striving to push out thespokes, rip the tires from therim, jam the axles through thehubs! Even the banked track can notoffset that pressure altogether. And that same pressure, lessonly in degree, hits your wheelhubs every time you turn a streetcomer, every time your wheelsare in a rut, every time you goover a hole or a stone. One of the biggest engineeringproblems in the motor car indus-try would have been to find someway to keep that side pressure—end-thrust, they call it—fromwearing out wheel hubs, axleends, and wheel bearings, i
