| COMPLETE FRONT AXLE WITH CROSS STEERING TUBE ETC WEIGHT SUFFICIENT TO BRING FRONT SPRINGS FLAT WEIGHT CARRYING TRAY IN PIT PULLEY WHAT WE WANT TO KNOW IS - (a) THE LOAD AND RADIUS OF PULL WHICH CAUSES FAILURE. (b) WHAT PART FAILS FIRST. THE GENERAL BEHAVIOUR OF THE FRONT AXLE SYSTEM UNDER A TORQUE AS SHEWN VIZ. WHAT DO THE FRONT SPRINGS DO - DOES THE I-SECTION AXLE TWIST MUCH - DO THE SPRING U-BOLTS APPEAR TO MOVE MUCH - DOES THE CROSS STEERING TUBE DEFLECT MUCH - ETC. ETC. SUGGESTED RIG | ||
