1.0 Abstract The elastic modulus‚ yield point‚ and ultimate strength of mild steel were determined in uniaxial tension. The "dogbone" specimen geometry was used with the region of minimum cross section having the dimensions: thickness =1.04 mm‚ width = 3.14 mm‚ and length section = 30 mm. This experiment was accomplished by first placing our specimens one at a time into a tensile testing machine (A G.U.N.T Hamburg Tensile Testing Machine (Max. load = 2kN))‚ which‚ under physical control‚ slowly

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

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
