Answer:
1 . stress - The measure of pressure exerted on a material.
2 . inclined plane - A hill or ramp used to make work easier.
3 . technology Application of science to practical uses.
4 . tensile strength - The measure of stress at the moment of tearing apart.
5 . shaduf - A device used by the ancient Egyptians to fill their irrigation ditches from the Nile River.
6 . expansion - The enlargement of material when heated.
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.
Explanation:
1 . Stress is the measure of pressure exerted on a material.
2 . A hill or ramp used to make work easier is known as an incline plane. They facilitate the easier and more accessible way of working.
3 . Technology is the application of science to practical uses.
4 . Tensile strength is the measure of stress at the moment of tearing apart.
5 . Shaduf - A device used by the ancient Egyptians to fill their irrigation ditches from the Nile River. They are still used in parts of India and the Egypt for irrigating their lands.
6 . Expansion is the enlargement of material when heated.
7 . An engineer is a scientist engaged in applying scientific principles to the invention or manufacture of machines.
8 . A water mill is a device that uses running water to grind grain.

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.
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.
