Question

Please I need help strength of materials tensile strngth of steel report please answer all these questions..thank you .

Answer the Following Questions: 7) Discuss the differences in the shapes of the stress-strain curves for the different types of materials tested (Not required) 8) Define the four fundamental mechanical properties: a) Yield strength b) Young's Modulus cUltimate strength d) Ductility 9) Discuss the importance to ensure axial alignment of the test specimen 10) Why stress and strain are more significant than force and elongation? 1) What is the difference between resilience and toughness of a material?

Answer 1

Stress strain curve for different types of material (2) for linear elastic materials (3) non liner elastic materials (4) elastic plastic without (strain measuring) (5) elastic plastic with strain measuring (60 ideal rigid \r\n (a) yield strength yield strength that properly of material by the virtue of which, on applying the stream in any material from which paint the material begin to deforms in that paint the value of stress is known as yield strength young�s modulus E = stress/strain (always normal)/(always longitudinal) it shown stiffness or elasticity of material E_s rightarrow 210 GPa (c) ultimate strength ultimate strength of any material in known and the value of stress which a material can resist without failure or stress @ which the material break is known as ultimate strength (d) ductility ductility in the property in which on applying the tensive force a material can deform without or on applying tensile force
