Elastic modulus of a composite

Assignment Help Mechanical Engineering

Carbide cutting tools are composites of very hard tungsten carbide particles   in a cobalt matrix. The elastic moduli of tungsten carbide and cobalt are 102 × 106  and 30 × 106  psi, respectively. It was experimentally found that the elastic modulus of a composite containing 52  vol.% carbide was 60 × 106 psi. What value of the exponent n in Equation (21.26) would this measurement suggest? A trial and error  solution is necessary to solve this. Note that n = 0, is a trivial solution.
