What do you call every little impact on the road then? Every bump is a 'sudden impact'. Those shock and vibe tables only go up and down 2 or 3 mm and they can generate tremendous forces.

Every little bump is basically 2x your weight being deflected by the cantilevered axle at whatever the change is.

You're definitely going to need a qualified metallurgist to figure your numbers... and then add in their safety factor.
