In this article, on the first table, I have compared the differences between the mechanism and machine. On the second table, I have compared the differences between the structure and machine.
The difference between Mechanism and Machine are listed below in tabular form.
|1||Mechanism transmits and modifies the motion.||Machine changes the mechanical work.|
|2||A mechanism is an outline of the machine to produce define motion between various links or joints Fig. 1).||Machine will have many mechanisms for transmitting the mechanical work or power.|
|3||Where kinematic chain is analyzed as a mechanism, no special consideration need to be given to the formed cross-section of the links.||In a machine, cross-section and proportions are to be considered to give stiffness, strength, and clearance to the paths of the machine.|
|4||Examples of mechanisms are clocks, typewriter, steering mechanism in a car, etc.||Examples of the machine are slotting, lathe, shaper in the workshop, (Shaper receives mechanical power which is suitably converted to do the work of cutting the metal), etc.|
The difference between a machine and structure are listed below in tabular form.
|1||In structure, no relative motion exists between its members.||In machine, relative motion exists between its parts.|
|2||Members meant for carrying loads are subjected to straining action.||Machine links are meant to transmit motion and forces which are dynamic (both static and kinetic).|
|3||Structure serves to modify and transmit forces.||Machine serves to modify and transmit mechanical work.|
|4||Examples of structures are roof trusses, bridges, building and machine frames.||Examples of machines are a slotting, shaper, lathe, and screw jack.|
