the design requirements of a structure. The compressive strength of concrete is the most common performances measure used by engineer in designing buildings and other structures. The compressive strength is measured by breaking concrete specimen in a compression-testing machine. The compressive strength is calculated from the failure load divided by the cross-sectional area resisting the load and reported in units of N/mm2. Compressive strength test results are primarily used to determine that the

determine the tensile strengths and tensile modulus of different materials by using the modern tensile testing machine. General Purpose Polystyrene(GPPS)‚ High Impact Polystyrene(HIPS)‚ High Density Polyethylene(HDPE) and Polypropylene(PP) were the materials used as samples for this experiment. 3 specimens of each plastic were loaded into the machine and the average reading out of the 3 was recorded for more accuracy. Through this experiment‚ the plastic with the greatest tensile strength was GPPS with

Weight training is a type of strength training that uses weights for resistance. Weight training provides a stress to the muscles that causes them to adapt and get stronger‚ similar to the way aerobic conditioning strengthens your heart. Weight training can be performed with free weights‚ such as barbells and dumbbells‚ or by using weight machines. Weight lifting is a crucial part of any athlete or active person‚ but studies show that weight lifting can be beneficial to the every day person‚ and

soil. Cylindrical compacted soil and cubic lime specimens with different proportions of the shells and fly ash are made to study the strength variance. Soil‚ which is classified as CL in the USCS system‚ commercialized pulverized oyster shell‚ F-type fly ash‚ and lime are mixed in different weight percentages. Five sample groups are made to study the compressive strength of soil and lime specimens‚ respectively. The lime cubes are made with 0.45 W/B ratio and the cylindrical soils are compacted under

Introduction Sociology is defined as the systematic study of human society. At the heart of sociology is a distinctive point of view called "the sociological perspective." Sociologists look for general social patterns in the behavior of individuals as they relate to a group and how the group and social structures affect our individual perception and behavior. Human behavior is patterned‚ and repetitive. We can predict with reasonable reliability what each of us will do generally under given conditions

Tensile Testing Of Metallic Materials 概要： Tensile testing of metallic materials is specified according to European EN 10002 standard. In this article the terms‚ definitions and designation for tensile test made at ambient temperature is described. The test involves straining a test piece in tension‚ generally to fracture‚ for the purpose of determining mechanical properties. Tensile testing of metallic materials is specified according to European EN 10002 standard. This standards consists of five

thinned down in the middle‚ thus making the material lighter. It has an excellent strength to weight ratio obtained from heat-treatment used in its formation. The heat treatment used for this steel does not use quenching rather uses air cooling or air hardening. This results in the steel having a finer grain and raises the yield strength in the material. Subsequently due to air hardening the material’s strength increases as the materials temperature cools. This unique air hardening property of

Perspectives on Gender Life is completely different living in the shoes of a woman rather than a man. Not only because of the stiletto heels but also from the obstacles thrown on the path. What it means to be a women today has changed significantly from the past‚ especially when relating to the United States. The range of opportunities may have increased for the female population‚ but they still have a more tough battle to fight. To be a woman in today’s society requires a large amount of strength
