Stiffness measurements on SAB 'hard' rubber pads (IM-SI-009)

1. The test set up is shown diagramatically in fig.1. The thickness of the rig members approximates to that of the corresponding wheel components. 2. Vertical deflection was measured by a linear potentiometer (Penny-Giles) output to a 'Bryans' X-Y plotter, Load was measured by a 45 kN load cell...
