Question: the mechanical properties of cobalt may be improved by incorporating fine particles of tungsten carbide (wc). given that the moduli of elasticity of these materials are, respectively, 200 gpa and 700 gpa, plot modulus of elasticity vs. the volume percent of wc in co from 0 to 100 vol% using both upper- and lower-bound expressions to form a performance envelope into which the material will fall. remember that the isostrain case is the upper-bound case and the isostress is the lower-bound case. mechanical properties: mechanical properties to identify and classify the materials. the most common mechanical properties are ductility, tenacity, strength, impact resistance, hardness. the mechanical property does not depend on the quantity of the material.

The weights of bags filled by a machine are normally distributed with a standard deviation of 0.05 kilograms and a mean that can be set by the operator. at what level should the mean weight be set if it required that only 1% of the bags weigh less than 9.5 kilograms? round the answer to 2 decimal places.
