What is Rubber band: Definition and 66 Discussions

A rubber band (also known as an elastic band, gum band or lacky band) is a loop of rubber, usually ring or oval shaped, and commonly used to hold multiple objects together. The rubber band was patented in England on March 17, 1845 by Stephen Perry. Most rubber bands are manufactured out of natural rubber or, especially at larger sizes, elastomer, and are sold in a variety of sizes.
Notable developments in the evolution of rubber bands began in 1923 when William H. Spencer obtained a few Goodyear inner tubes and cut the bands by hand in his basement where he founded Alliance Rubber Company. Spencer persuaded the Akron Beacon Journal as well as the Tulsa World to try wrapping their newspapers with one of his rubber bands to prevent them from blowing across lawns. He went on to pioneer other new markets for rubber bands such as: agricultural and industrial applications and a myriad of other uses. Spencer obtained a patent on February 19, 1957 for a new "Method for Making Elastic Bands" which produced rubber bands in an Open Ring design.

    Designing a 13 Second Flight with a Rubber Band

    im to design something, a plane, or any kind of material to let it stay from the time of release up to it falling into the ground for 13 seconds provided that it is powered by a rubber band... i'm having a hard time thinking about it, having it stay in mid-air longer than usual, and just want...

    Distance of an object launched by a rubber band decreases as its mass increases

    I need to prove that the distance of an object launched by a rubber band decreases as its mass increases, algebratically. Can anyone help me? Thanks.

    Solving a Cute Problem: Rubber Band on a Frictionless Cone

    Here's a cute problem I came across recently. Suppose you have a rubber band with spring constant k, mass m and unstretched radius r. Now suppose you have a frictionless cone and the angle of the peak is 2 \theta (that is, if you project the shape of the cone onto a plane it looks like a...

    Rolling Can with Rubber Band and Plasticine

    Imagine that now i have a can. I poke a hole at the centers of both the bottom and the cover of the can. Then i tie a rubber band onto the holes that it goes across the tin from the hole at the bottom to the hole on the cover. After that i stick some plasticine onto the rubber band. When i roll...

    Elastic Properties of a rubber band

    Hi all. I have something of a problem in my understanding of a current lab experiment that I am doing in my second year. The experiment is set such that we explore the elastic properties of an elastic band through small and large deformations and measure the force that it exerts on the...

    Thermondynamics: Ideal Rubber Band

    Set-up: Rubber band modeled as an Ideal chain (polymer) with Nr (links) monomers pointing right, and Nl monomers pointing left each of length l. Find expressions for the length of the band, its statistical weight (iI think that means the multiplicity?) and its entropy, in terms of Nr and Nl...

    Need help on rubber band and Hooke's Law

    This has caused me to be very confused because at one time i did an experiment, the rubber band followed Hooke's Law, but at another time, it does not. When I search the internet, some websites state that such experiments are only correctly done when the force is linear with the extension...

    Exploring the Science of Rubber Bands: The Force Behind Elasticity

    OK, maybe this is an odd question, but here goes: When I pull on a rubber band, is the force I "feel" the resistance to co-valent bond separation? Am I actually "feeling" electron forces?
