For mild steel, the lower yield point is more significant than the upper yield point because Strain is more than at this point It is less than upper yield point It is less affected by the shape of the section None of the above2. The modulus of elasticity of high tensile steel is Smaller than that of mild steel Equal to that of mild steel Larger than that of mild steel Equal to that of aluminum3. In an experiment, it is found that the bulk modulus of a material is equal to its shear modulus. The Poisson’s ratio is 0.125 0.250 0.375 0.5004. Consider the following factors : Large number of loading cycles 2) Large variation in stress 3) Large stress concentrations Those associated with fatigue failure include 1 and 2 1 and 3 2 and 3 1,2 and 35. A cast iron block is 5cm2 cross-section carries an axial tension load of 10t. The maximum axial stress in the block is given by 2000 kg/cm2 1000 kg/cm2 500 kg/cm2 250 kg/cm26. For engineering materials, Poisson’s ration lies between 0 and 1 -1 and +1 -1/2 and +1/2 0 and 1/27. The shear modulus of most materials with respect to the module of elasticity is More than half Less than half Equal to half Unrelated8. As soon as the external forces causing deformation in a perfectly elastic body are withdrawn, the elastic deformation disappears Only partially Completely after an initial period of rest Completely and instantaneously Completely over a prolonged period of time9. The number of elastic constants for an isotropic elastic, material following Hooke’s law is: 2 9 21 3610. As compared to mild steel ,high carbon steel has less Ultimate strength Hardness Ductility Hardness and ductilityBe sure to click Submit Quiz to see your results!Please enter your mail id to get the correct answers on your mail.
