In regards to the W12x24 steel beam, what does the number represent?

• A. Pounds per linear foot
• B. Inches in depth
• C. Weight in tons
• D. Height in inches

Answer: (A)

The designation of W12x24 for a steel beam provides specific information about its dimensions and weight characteristics. The first number, '12', indicates the nominal depth of the beam in inches, while the second number, '24', signifies the weight of the beam in pounds per linear foot. This means that a W12x24 beam weighs 24 pounds for every linear foot of its length. Understanding this nomenclature is crucial in construction and structural engineering, as it helps in selecting the appropriate beam based on the required strength, load-bearing capacity, and space considerations. Thus, identifying that the second number directly corresponds to the weight in pounds per linear foot is key to comprehending the specifications of steel beams.
