Classical models of deformable solids suppose these solids as the passive objects, which are subjected to some outside forces. Living organism is not a passive object and when outside forces act on this organism it shows an answering reaction. This effect can be especially seen in the case of dynamical loading and at the dynamic problems solution. Reaction of living organism has a biological character and can be named as “biofactor”. As an example the problem of steady-state vibration in a human arm is considered. Presence of a small parameter allows to receive the solution as a series expansion. Analysis was made numerically with two first terms of series under constraint. It occurs that presence of an answering reaction has a great influence on the results. All depends on time delay and values of acting load.
