Force Of A Stretched Rubber Band

Which force is applied to a rubber band to make it stretch.

Force of a stretched rubber band.

Everybody knows that when you apply a force to a spring or a rubber band it stretches. Stretching a rubber band is like moving a brick from the floor to the table top. You can easily measure the force produced by a drastically stretched rubber band. Rubber is a member of a larger class of materials called elastomers and it is difficult to overestimate their economic and.

Rubber elasticity refers to a property of crosslinked rubber. But the standard theory of rubbery materials can t predict this force. Pull horizontally on the rubber band with the force probe until the band is stretched to the same standard length used in activity 1 1 and begin graphing while holding the rubber band steady for the whole graph. Shoot more rubber bands in the same way except stretch them back to 15 cm 20 cm 25 cm or 30 cm.

The work done in stretching the unstretched rubber band by l is. It takes more force to stretch them the farther you pull. Both springs and rubber bands have a special property. In this case both electromagnetism and gravity coul.

A physicist would ask how is the force that you apply related to the amount of stretch every physics experiment has a purpose often phrased as a question that the experiment hopes to answer. After each launch have your helper. I m not sure this question has an obvious answer because parsing your question isn t straightforward. In the 16 february physical review letters researchers make theory agree with experiment by taking into account a previously neglected aspect of the way rubber molecules move.

Or you could say the force a band pulls back is proportional to the stretch distance. Attach one end of a rubber band to something that can t move as before and the other end to the force probe hook. When a rubber band is stretched by a distance x oscillation waves when a rubber band is stretched by a distance x it exerts a restoring force of magnitude f ax bx 2 where a and b are constants. Shoot at least five rubber bands for each stretch length.

This can be repeated many times with no apparent degradation to the rubber.
