15. Dynamicity

If a system is made up of parts which are all connected rigidly together, then any force applied to the system is felt equally by all parts. When things are fixed, then when their environment changes, they are unable to cope well with the change. Dynamicity means creating systems which are able to cope with change and intrusions from outside it. Separating parts, using suspension systems, flexible connections and cushioning all are methods of achieving dynamicity.
