What is the crushing strength of steel plate?

1. Tensile strength of 55,000 pounds per square inch

2. Crushing strength of 95,000 pounds per square inch

3. Tensile strength of 95,000 pounds per square inch

4. Crushing strength of 55,000 pounds per square inch

The correct answer is: Crushing strength of 95,000 pounds per square inch

The crushing strength of a steel plate refers to its ability to withstand compressive forces without failing. In structural engineering and material science, this property is vital for ensuring that materials can support loads without buckling or collapsing. The value of 95,000 pounds per square inch represents a typical crushing strength for certain types of steel plates under compressive loads. This strength is a measure of how much force the steel can handle per unit of area before failure occurs, making it a key parameter in applications where steel is subjected to compressive stresses, such as in beams, columns, and other structural components. The other options mention tensile strength values, which refer to a material's ability to withstand tension and pulling forces. While tensile strength is an important property, it does not directly relate to crushing strength, which specifically involves compression. Knowing the distinction between these properties is crucial for designing safe and effective structures, particularly in applications related to low-pressure boilers, where understanding the limits of materials under various stress conditions is key to operational safety.
