What Is The Elasticity Of Rubber Bands

The way to think of the elasticity is in terms of entropy which is basically a measure of disorder.

What is the elasticity of rubber bands.

The science of rubber. This can be repeated many times with no apparent degradation to the rubber. A rubber band also known as an elastic band gum band or lacky band is a loop of rubber usually ring shaped and commonly used to hold multiple objects together the rubber band was patented in england on march 17 1845 by stephen perry. Materials like rubber have a high elasticity.

This is because it is made up of millions of long and bendable chains of molecules. Rubber is a member of a larger class of materials called elastomers and it is difficult to overestimate their economic and. Ever wonder what holds your underpants up or why a rubber band stretches so much. Rubber isn t a manmade creation although we do use it in countless applications to make our life easier.

Yes a rubber band will actually become softer or easier to stretch when the temperature gets colder. Today rubber bands are most commonly used to hold multiple items together. You can apply stress on these chains in any direction but they will always return to their original shape. Rubber elasticity refers to a property of crosslinked rubber.

The rubber bands in freezing water were the opposite with a stretching length of 9 50 o o5 cm 0 c. When the rubber bands were heated the particles stretched out making them more elastic and able to withstand greater force. In fact natural rubber is a special type of chemical compound called an elastomer composed of unique molecules that can stretch to nearly double their normal length. Modifications to the original rubber band patented in england on march 17 1845 by stephen perry include aerobic bands bracelets and projectiles.

Effect of temperature on the elasticity of a rubber band table. The hypothesis was supported by our experiment. The rubber band s elasticity water resistance and lightness have made it a universal commodity. Using the scissors cut one rubber band so that it is a straight ribbon rather than a circle.

Gently being careful not to burn yourself on the hot water or steam lower the weight and rubber band into the graduated cylinder. Why do rubber bands lose their elasticity. It can be stretched by up to a factor of 10 from its original length and when released returns very nearly to its original length. When frozen the particles contracted adding strength and increasing resistance to force.

Rubber band elasticity and temperature from science buddies science activities for all ages from science buddies. Stretching to the farthest extends of 17 90 o o5 cm 100 c. Our results also showed that the effect temperature had on the elasticity of the rubber bands was amplified under more weight. Tie one end of the rubber band to the middle of the skewer and the other end to the hook or knob on the steel weight.
