Temperature Effects on the Elasticity of Rubber Bands

It shrinks because as the molecules in the rubber become heated, they also become less aligned and contract, causing the rubber band itself to shrink. This simple experiment can be performed by using weights to stretch the rubber band 2 4 times its original length, then heating it with a hair dryer.

May 01, 20130183;32;A stretched out belt is not out of the ordinary and doesnt necessarily mean that there are any other problems with your vacuum. Because rubber belts get pretty warm during normal operation, and are stretched to ensure the necessary tension to drive the brush roll, stretching / relaxing of the belt material occurs naturally over time.

Chart of tensile strength of rubber This indicates the minimum tensile strength of the elastomer. If the designation has an M after the Revision Year, then this callout is stated in Metric units, megapascals (MPa). If no M is present, then the callout is specifying the English unit, pounds per square inch (psi). In this example, the 14 is calling out 14 MPa.
