The observed parameter includes crosslink density‚ tensile strength‚ tensile modulus and elongation at break. The morphology of film was studied via Scanning Electron Microscope (SEM). The results

High strength to weight ratio‚ environmental resistance‚ high stiffness and good wear resistance are the characteristics that encourages more research to develop their applications with further improvement in the properties. Ceramic particles such as SiC‚ Al2O3‚ B4C‚ TiC and TiB2 are the widely used materials for reinforcement of aluminium [1]. Boron carbide (B4C) is one of the most promising ceramic materials due to its high strength‚ low density (2.52 g/cm3)‚ high hardness

Muscular strength Muscular strength is about how much weight you are able to lift with your muscles at one time. This would relate to the “quality” of the task being performed as opposed to the frequency‚ which is dealt with by your muscular endurance. It is the maximal lift

On the one hand‚ as we all know‚ exercises not only improve muscle and strength but also strengthen bones and reduce body fat. Regular physical activity has always been credited with increasing physical fitness. But it is said that what affects our physical selves affects our psychological and emotional selves as well‚ and that

Training meets Sham. Basically‚ physical exercise is defined as any bodily activity that enhances or maintains physical fitness and overall health and wellbeing. There or many reasons people work out. To build muscle‚ to fight disease‚ to build strength. Maybe pass that PT test. People work out to lose weight and to build those cardiovascular muscles. Frequent and regular physical exercise boosts the immune system‚ and helps prevent diseases such as heart disease‚ cardiovascular disease‚ type 2

Health-related Physical Fitness – The four components of health-related fitness are cardiovascular endurance‚ body composition‚ flexibility‚ and muscular strength and endurance. • Cardiovascular endurance is the ability of the heart‚ blood vessels‚ and respiratory system to work efficiently delivering oxygen to the muscles for an extended period of time.

construction of the end product. This test is usually done prior to any decision being made on the materials use. The theory behind tensile testing is to measure the stress-strain response of the material. By doing so you obtain the yield strength and ultimate tensile strength as some of the results and also provides information on how brittle/ductile the material is‚ which is vital in the future usage of the material in testing. In this test the aim was to perform tensile tests on standard steel‚ Aluminium

comparison‚ the processing conditions were kept same for the fabrication of Al-CNT composites. In Al-CNT composites’ specimens‚ the yield and tensile strengths increased from 29 MPa and 56 MPa to 97 MPa and 109 MPa‚ respectively. However‚ a decrease in elongation from 22.6 % to 7.4 % was observed. It is believed that the amelioration of mechanical strengths is a synergistic effect of the strengthening by the nanotubes‚ increased lattice strain and refinement in crystallite size.
