I am trying to design a bicycle cargo rack that uses shock absorbers to protect sensitive equipment (i.e. a laptop computer). I have data for the maximum height from which laptops can fall without damage as well as the maximum acceleration to which they may safely be subjected. I am planning to do an experiment that measures the change in acceleration of a bicycle riding over a bump at ordinary travel speeds. I would like to use this data to select appropriate shock absorbers for my purpose. My problem is that I am unsure how to identify the appropriate quantities (i.e., force, energy), and relate them to the appropriate parameters of a shock absorber(damping coefficient etc.). My specific questions are: 1) (Assuming force is the appropriate qty) How can I relate the fall height of a computer to the force it sustains on impact? 2) If I can measure the change in acceleration of the bicycle, how can I relate this to the force applied specifically to the cargo load (as opposed to the cargo load, bicycle and rider)? 3) Once I determine the force to which the load is subjected, how do I relate this to the appropriate parameters of the shock absorber? Any insight you may be able to provide is greatly appreciated! Sorry for the long post.
