The basic problem of mechanical design is why bicycles are not machines, but institutions
The bicycle becomes the organization, the most important characteristic is he does not have the power. Cannot say the human this power also can calculate the power. If this kind of change, a pair of scissors also may say is the machine, because he also has the power: manpower forceIf a bicycle leaves the human body, it can not accomplish the transformation of energy, so it is not a machine, but a mechanism
Machines are made up of various institutions that can perform energy conversion or do useful work, such as internal combustion engines, planer, etc.
