Modulus of Elasticity of Steel
The modulus of elasticity, also known as Young's modulus, is a material property that describes the stiffness or elasticity of a material. It is defined as the ratio of stress to strain within the elastic region of a material. In other words, it measures the resistance of a material to deformation when subjected to an external force.
Steel is a commonly used material in various industries and applications due to its excellent mechanical properties, including high strength and stiffness. The modulus of elasticity of steel determines its ability to withstand deformation under applied loads.
Options:
a) 2×104 MPa
b) 1.2×105 MPa
c) 2×105 MPa
d) 2×106 MPa
To determine the correct answer, we need to understand the typical range of the modulus of elasticity for steel.
Modulus of Elasticity Range for Steel:
The modulus of elasticity of steel can vary depending on its composition, heat treatment, and other factors. However, a commonly accepted range for the modulus of elasticity of steel is between 190 GPa (Gigapascals) and 210 GPa. This is equivalent to 190×103 MPa and 210×103 MPa, respectively.
Comparing the given options with the typical range of the modulus of elasticity for steel, we can see that option 'c' (2×105 MPa) falls within this range.
Therefore, the correct answer is option 'c' (2×105 MPa).
