O A cylindrical rod made from an unknown metal is 350mm long and has a diameter of 10mm. The rod is subjected to a tensile load. It experiences only elastic deformation and elongates by less than 1.0mm under an applied load of 19,800N. Could any of the four metals listed in the table below could be the unknown metal? If so which ones and why?

Which one(s) of the following about G, shear modulus of elasticity of a material are correct? select all which are correct. G is also called the modules of rigidity. G is related to the modulus of elasticity E and Poisson’s ratio . G is usually smaller than Young's modulus E for the same material. G is the ratio of shear stress to shear strain when the material's proportional limit in shear has not been exceeded.
A nodukat or ductile cast-iron is identified by the ASTM with a three part grade designation. And example of the gray designation is a 55 Dash 35 Dash 25 nodular cast iron. This designation has the following meeting. 55 is the tensile strength in KSA, 35 is a yield strength and KSI, and 25 represents 25% elongation. Another jeweler or ductile cast-iron is identified by the a STM with a three part grade designation. And example of the gray designation is a 55 -35 -25 nodular cast iron. This designation has the following meeting. 55 is the tensile strength in KSA, 35 is a yield strength and KSI, and 25 represents 25% elongation percent elongation. True or false
