7 . engineer Scientist engaged in applying scientific principles to the invention or manufacture of machines.

8 . water mill A device that uses running water to grind grain.

Step-by-step explanation:

The reasons behind these answers are:

1.- stress is the effect of pressure on an object.

2.- An Inclined plane is an inclined terrain that unites two different plain pieces of terrain at different elevations. Its purpose its to ease movement and transport between them.

3.- Technology is the employment of science to easy human life.

4.- Tensile strength is the amount of stress an object can support before breaking.

5.- The shaduf was a device employed in different ancient civilizations to irrigate land from ditches.

6.- Expansion is the phenomenon that occurs when a material or object is heated and it wides space its mass occupy.

7.- They are scientists that use science to solve problems.

8.- A watermill is an object that uses water to develop strength by the means of a grind and allows it to be used.
