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

Muscular Strength Muscular strength is the ability of a muscle or group of muscles to exert a force against a resistance in a single contraction. Strength is fundamental for all sports 3. Muscular Endurance Muscular endurance is the ability of a muscle to exert a force repeatedly over an extended period of time. 4. Flexibility

OBJECTIVE To ensure and guarantee the safety of flight‚ the materials in an aircraft used is an important element. This includes small parts like nuts‚ bolts and screw. The materials are chosen because they must have a certain features like light and extremely strong This project looks into the parts of an airplane mainly the wing. The wing of an aircraft comprises of skin‚ spar‚ ribs and stringer. We will further discuss into the properties‚ test standards and factors of the materials being chose

Physical fitness can improve not only body health but also mental health. Physical exercises improves muscle and strength but also strengthen bones and reduce body fat. Regular physical activity has always increased physical fitness. It is said that what affects our physical selves affects our psychological and emotional selves as well. Physical activity enhances both

Until now‚ most of the emphasis in sports training has been focused on the classical triad of muscular strength‚ cardiovascular conditioning‚ and neuromuscular coordination. Some alternative physical training activities - such as Pilates‚ yoga‚ Continuum Movement‚ Tai Chi‚ Qi Gong and martial arts – are already taking the connective tissue network into account

measure the mechanical properties of a material is the Tension Test. Tension test is widely used to provide a basic design information on the strength of materials and is an acceptance test for the specification of materials. The major parameters that describe the stress-strain curve obtained during the tension test are the tensile strength (UTS)‚ yield strength or yield point (σy)‚ elastic modulus (E)‚ percent elongation (∆L%) and the reduction in area (RA%).
