| -2- Our recommendation is that we only try the stiffened yoke for the time being, and that we continue to use our present proportion of front braking. We can introduce a thrust washer into the upper bearing if absolutely necessary, or use a spherical bearing. We will repeat these tests with the stiffened yoke and we are building a brake torque endurance rig. [Diagram annotations and calculations] 1,000 lbs 400 lbs a M 14,500 lbs-ins 1,400 lbs 10" M = 14,500 - 4,000 - 1,000 a = 10,500 - 1,000 a lbs-ins. If a = 7.15", M = 3,350 lbs-ins. If a = 3.6", M = 6,900 lbs-ins. | ||
