In this topic you study, the difference between machine and mechanism.
| Machine | Mechanism |
| Machine transmits or modifies the available energy into some (useful) kind of desired work. In simple words, machine modifies mechanical work. | Mechanism only transmits or modifies motion. |
| Machine is constructed or built on the skeleton of mechanism considering strength requirement for desired application. | Mechanism is a skeleton for any machine, which ¡s designed for getting the required motion. |
| Dimensions and shape of links are very important parameters to give stiffness and strength to machine. | When kinematic chain is analysed as mechanism, dimension of link is not so important parameter. |
| Examples : Steam engine, Reciprocating pump, Lathe etc | Examples : Slider-crank mechanism, Pump mechanism, Four bar chain mechanism, Quick return mechanism |
