Thus the engine makes a machine do one predefined thing..Same happens in a fourbar for example it is forced to move along its path by a motor/powersource/engine. This makes them machines. | |

| Nov 28, 2016 at 20:30 | comment | added | BarbalatsDilemma | @joojaa maybe I misunderstand your point, but wouldn't a locomotive have 1 DOF (forward and backward along the train track)? | |
| Nov 28, 2016 at 20:27 | comment | added | joojaa | according to the definition i have seen a mechanical machine is one that has no degrees of freedom once attached to one engine. So for example a robot is not a machine in this terms. But many machines. Wereas a steam locomotive is a machine (adjustable controlls are still permitted) | |

| Nov 28, 2016 at 18:33 | comment | added | Hamed Begloo | Thank you for your helps. I voted your answer up but since I want to see others' opinions as well I prefer to make question to be remained open. Thank you again. | |
| Nov 28, 2016 at 18:29 | comment | added | BarbalatsDilemma | @Hamed I suppose since a mechanism would need to be grounded with respect to some reference in order to do anything useful that definition also works. As for the mechanical machine, if you connect a mechanism to another mechanism, are they still separate mechanisms or do they form a single, larger mechanism? Can a machine be constructed from a single mechanism? In these cases it all depends on the terminology you want to use, and how much you need to divide your machine to describe it in a useful way | |
| Nov 28, 2016 at 18:22 | comment | added | Hamed Begloo | Thank you for your answer. I don't remember precisely but I think I read somewhere that a Mechanism is a Linkage/Kinematic chain with at least one grounded joint and a Mechanical machine is any group of connected mechanisms. Do you agree with these definitions too? | |
