Sc1 Investigation: How Easily A Material Stretches under Pressure

Apparatus:

image10.pngimage02.pngimage11.pngimage03.pngimage08.pngimage12.pngimage09.pngimage01.pngimage06.pngimage07.png

Diagram:

 The diagram shows an example of a rubber band being stretched some weights. The way you set up this apparatus is you attach the rubber band and the ruler to the stand  and put the weights on the end of the material and then you just read the measurements.

Help:

 In this investigation I had 2 partners Fielde Fargason and Richard Hart.

Result Tables:

In this investigation ive done a lot of things to make the investigation is fair, safe

and accurate.

You can tell by the tables results that the spring stretched to much and the rest of the results could not be recorded.

From the results above you can tell that the spring was quite loose because every 1N added to the spring it stretched by at least 1 cm.

You can tell by the results above that a plastic bag doesn’t stretch a lot. When we tested it for the second time the bag was already stretched into a new size so the two different results in the columns named 1 +2 should be quite different.

    Then, what happens when the white dwarf forms depends on the mass of the star. Stars like the Sun would just fade away but white dwarfs with a mass greater than about 1.4 times the Sun?s mass can either explode into smaller white dwarfs or collapse suddenly and become an intensely bright supernova.
