Discuss how stress relaxation and viscoelastic creep tests are conducted. Cite the experimental parameter of interest for each of these tests with emphasis on how it is determined. Give two examples of plastic products or components in which you think that creep and stress relaxation would be important considerations.

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
