1. The mechanical properties of cobalt may be improved by incorporating fine particles of tungsten carbide (WC). Given that the mod- uli of elasticity of these materials are, respec- tively, 200 GPa (30 x 106 psi) and 700 GPa
2. (a) What is the distinction between cement and concrete?
(b) Cite three important limitations that restrict the use of concrete as a structural material.
(c) Briefly explain three techniques that (102 x 106 psi), plot modulus of elasticity are utilized to strengthen concrete by rein versus the volume percent of WC in Co from 0 to 100 vol%, using both upper- and lower- bound expressions.
