In materials science, a general rule of mixtures is a weighted mean used to predict various properties of a composite material. [ 1 ] [ 2 ] [ 3 ] It provides a theoretical upper- and lower-bound on properties such as the elastic modulus , ultimate tensile strength , thermal conductivity , and electrical conductivity . [ 3 ]
Here, a A (1-x) B x is the lattice parameter of the solid solution, a A and a B are the lattice parameters of the pure constituents, and x is the molar fraction of B in the solid solution. Vegard's law is seldom perfectly obeyed; often deviations from the linear behavior are observed. A detailed study of such deviations was conducted by King. [3]
Reuss (1929) [5] - Stresses constant in composite, rule of mixtures for compliance components. Strength of Materials (SOM) - Longitudinally: strains constant in composite , stresses volume-additive. Transversely: stresses constant in composite, strains volume-additive.
The Wilke mixing rule is capable of describing the correct viscosity behavior of gas mixtures showing a nonlinear and non-monotonical behavior, or showing a characteristic bump shape, when the viscosity is plotted versus mass density at critical temperature, for mixtures containing molecules of very different sizes.
Word problem from the Līlāvatī (12th century), with its English translation and solution. In science education, a word problem is a mathematical exercise (such as in a textbook, worksheet, or exam) where significant background information on the problem is presented in ordinary language rather than in mathematical notation.
The 911 call came in at about 4 p.m. on Sept. 18, 2014, to Gilchrist County dispatchers in Florida. On the tape, the 911 operator could hear a man admitting to killing his adult daughter and his ...

From January 2008 to July 2011, if you bought shares in companies when Judy C. Lewent joined the board, and sold them when she left, you would have a -30.3 percent return on your investment, compared to a -10.3 percent return from the S&P 500.
