was tested three times using an Instron load frame and the BlueHill data acquisition software. The data from each test was used to determine valuable material properties such as ultimate tensile strength‚ modulus of elasticity‚ and yield strength. Other calculated properties included true fracture strength‚ percent reduction of area‚ and percent elongation. These material properties were used for comparing the materials to each other‚ and to define the material as brittle or ductile. The true stress

The Truth About A Quick First Step What is a First Step The first step is basically the first step you take of the dribble‚ when driving towards the basket‚ in order to beat your opponent to the hoop. It does take the right strength‚ coordination‚ and the right boost of energy‚ which is required from the leg you typically use to make your first step‚ but to become a better player‚ you should condition both legs to be able to take the first step when driving to the hoop. You will find that with the

CHAPTER 15 COMPOSITES PROBLEM SOLUTIONS Large-Particle Composites 15.1 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 (30 × 106 psi) and 700 GPa (102 × 10 psi)‚ plot modulus of elasticity versus the volume percent of WC in Co from 0 to 100 vol%‚ using both upper- and lower-bound expressions. Solution The elastic modulus versus volume percent of
