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.

Rule of mixtures 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. It provides a theoretical upper- and lower-bound on properties such as the elastic modulus, mass density, ultimate tensile strength, thermal conductivity, and electrical conductivity. In general there are two models, one for axial loading (Voigt model), and one for transverse loading (Reuss model). In general, for some material property formula_1 (often the elastic modulus), the rule of mixtures states that the overall property in the direction parallel to the
