designed to measure physical strength‚ agility‚ and endurance’. Individual Physiological Response to Exercise Fitness Components & Aerobic Dance Strengths: Muscular endurance is the ability to work a muscle for long periods at less than maximum effort where local fatigue rather than general exhaustion is the limiting factor. I would find muscular endurance as one of the fitness components I am strongest at as in the 3RM Bench Press as I lifted above average. This strength is evident in the aerobics

is the time on the when last sample breaks ( ±5 s)? = 2.55 s Abstract Polystyrene is hard but brittle thermoplastic‚ less flexible and ductile at room temperature than Polyethylene because the phenyl group in its repeating unit increases the strength of intermolecular forces present in crystalline due to its weak polarity. Polystyrene has a modulus of elasticity (initial modulus) of 1.16 ± 0.3 GPa‚ breaking stress (UTS) 36.12± 6.3 MPa. Polyethylene (HIPS and UHMWPE) are ductile‚ flexible thermoplastic

Accordingly‚ the training and career development initiative is an internal strength and external weakness. As an internal strength‚ AFLAC values corporate knowledge and takes an active role to cultivate internal promotions. On the same notion‚ a large degree of internal promotions can be an external weakness as it limits outside experience‚ which can diminish innovation and narrow perspective (Gomez-Mejia et al.‚

test the tensile stress and compressive strength of materials. It is named after the fact that it can perform many standard tensile and compression tests on materials‚ components‚ and structures. The range of the UTM available at the laboratory is 8 to 36 mm and has the capacity of 5 to 100 kN. D. TENSILE TESTING MACHINE The tensile testing machine is a specialized machine designed for tensile testing This measures how strong it is (tensile strength) how stretchy it is (elongation)‚ and how

Extensive studies have shown that in Sri Lanka Bamboo is a very suitable material for scaffolding during construction given its durability and strength. Bamboo is an extremely stable green reinforcement building appliance‚ it is easily accessible and readily workable (SAITM – RSEA 2013). 4.2 Physical and mechanical properties of Bamboo Bamboo and wood has a wide range of difference which is not

are‚ the material should contain high strength‚ modulus of elasticity‚ wear resistance‚ ability to withstand vibrations‚ and corrosion resistance. High strength is mostly concerned in diesel engines because of their high compression ratios compared with petrol engines. In diesel engine its compression ratios are normally 17:1 or greater‚ but in petrol engine it is nearly 10:1. The material also should have low density to reduce its weight but with higher strength. It should also have a low thermal expansion
