The Mixtures "In the Summertime" and—as a result of the 1970 radio ban, during which many Australian radio stations refused to play Australian and British music released by major labels—received much more airplay than had initially been expected for a group on a small record label. The single went to #1 in Australia for six weeks. They followed up with "The Pushbike Song" (produced by David Mackay), which went to #1 in Australia for two weeks, hit #2 in the UK Singles Chart, and went to #44 on the "Billboard" Hot 100 in the U.S. after being released on Sire Records. The
Rule of mixtures and can be combined to give Finally, since formula_20, the overall elastic modulus of the composite can be expressed as Now let the composite material be loaded perpendicular to the fibers, assuming that formula_22. The overall strain in the composite is distributed between the materials such that The overall modulus in the material is then given by since formula_25, formula_26. Similar derivations give the rules of mixtures for Rule of mixtures In materials science, a general rule of mixtures is a weighted mean used to predict various properties of a composite material made up of continuous and unidirectional fibers.
