Difference Between Machine and Structure

Comparison between Machine and Structure in Kinematics And Theory Of Machines(KTM)
Summary:
The Major Difference Between Machine and Structure is that the member Structure does not move relative to one other, whereas The part of the Machine move relative to one another. Machine converts energy into some useful work, whereas Structure does not convert energy into some useful work.
Comparison Chart
| Machine | Structure |
|---|---|
| Parts of a machine move relative to one another | Members of a structure do not move relative to one another |
| The machine transforms the available energy into some useful work | In a structure, no energy is transformed into useful work |
| Links of a machine may transmit both power and motion | Links of a machine may transmit both power and motion |
| Machine serves to modify and transmit mechanical work | Structure serves to modify and transmit forces |
| Example: roof trusses, bridges, buildings, and machine frames. | Example: slotting, shaper, lathe, and screw jack. |
Machine
- A machine is a mechanism or a combination of mechanisms that, apart from imparting definite motions to the parts, also transmits and modifies the available mechanical energy into some kind of desired work.
Structure
- It is an assemblage of a number of resistant bodies (known as members) having no relative motion between them and meant for carrying loads having straining action.
- A railway bridge, a roof truss, machine frames, etc., are examples of a structure.
