What is the "E" value of steel?

The "E" value, or modulus of elasticity, for steel is an important property that describes the material's ability to deform elastically when a force is applied. It is a measure of the stiffness of a material, indicating how much it will stretch or compress under a given load. In the case of steel, the accepted modulus of elasticity is approximately 29 million psi (pounds per square inch). This high value reflects steel's rigidity and strength, making it a preferred choice in construction and structural applications.

In comparison to the other values provided, 29 million psi accurately represents steel's performance characteristics, particularly in bearing loads and maintaining its shape under stress. The other options do not reflect the correct modulus of elasticity for steel and are typically associated with other materials or incorrect measurements for steel. Understanding the correct modulus of elasticity is crucial for engineers and professionals in deciding materials for construction, ensuring structural integrity and performance under various conditions.
