Definitions of The Concepts

DEFINITONS of THE 10 CONCEPTS

1. Circular motion is the motion where the trajectory of the moving thing is on a circle.

2. Load factor is the ratio of actual quantity to the maximum possible quantity, which can also be evaluated as efficiency.

3. Mass conservation means that the matter in an isolated or closed system never be destroyed or created, so its mass is conserved. 

4. Bernoulli’s equation is the equation stating the relationship between the speed and the pressure of the fluid (which is flowing horizontally) at two different points. 

5. Steam engine is an engine whose power is supplied by steam pressure.

6. Crank mechanism is an arm which is attached perpendicularly to a rotating shaft so that the reciprocating motion is transferred to the shaft.

7. Differential gear is a gear combination which transfers the power generated by the engine to driving wheels. 

8. Steady state is the state in a process or of a system that does not change with time.

9. Surface tension is behaving like a film of surface of liquids by the effect of cohesion forces. 

10. Pressure gage is a meter that measures and shows pressure of fluid.
