Shock [Example] for a product with a fragility factor of 40 G and an anticipated 1 m drop, The 53 mm deflection distance is the minimum stopping distance consistent with maintaining 40 G or less. Stopping in any lesser distance would raise acceleration to over 40 G and cause damage. The 53 mm deflection is the theoretical deflection distance, not the cushion thickness. To determine actual cushion thickness, it is necessary to know how far the 0.053m(53 mm) 40 - 2 2 1 =  = m DShock [Example] for a product with a fragility factor of 40 G and an anticipated 1 m drop, The 53 mm deflection distance is the minimum stopping distance consistent with maintaining 40 G or less.
