| BENTLEY III YOKE MOVEMENT DUE TO BRAKING TORQUE. LOAD. | Yoke Movement rel. to frame. | A.{Mr Adams} Yoke Bending. | B. Distortion of pivot pin etc. | C. Needle bearing clearance etc. | D.{John DeLooze - Company Secretary} Twist in neck. | E.{Mr Elliott - Chief Engineer} Backward movement of torque arm. --|---|---|---|---|---|-- 0 lb. | 0 | .003 | 0 | 0 | 0 | 0 | .001 | 0 | 0 | 0 400 lb. | .040 | .047 | .030 | .030 | .018 | .019 | .003 | .004 | .0005 | .010 | .010 800 lb. | .088 | .090 | .059 | .059 | .036 | .036 | .009 | .009 | .0005 | .0175 | .018 1000 lb. | .106 | .106 | .068 | .068 | .043 | .043 | .017 | .017 | .001 | .022 | .022 (Vertically written text next to column D): No Hysteresis. ANALYSIS OF DEFLECTION MEASURED FROM THE TOP OF THE YOKE. The above figures were taken with and without the recently fitted strut in the lower triangle. There was no apparent difference in the two readings. | ||
