FUNCTION

Definition

The function of a mechanical system is the transforming of the input

to the system into the output from the system.

Use

The purpose of modelling FUNCTION is to examine how a given

principle might be exploited as a possible solution to the problem.

The function model can become a starting point for syntheses,

resulting in a structure satisfying the desired function. The function

should be described without using structural elements
