Answer 1

The identification W8X15 refers to a wide-flange beam where 'W' indicates a wide-flange section, '8' approximates the depth of the beam in inches, and '15' is the weight per foot in pounds.

Step-by-step explanation:

The steel beam identification W8X15 represents a wide-flange beam with a weight of 15 pounds per foot. The 'W' stands for wide flange, the '8' indicates approximately 8 inches in depth or height of the beam, and the '15' denotes the weight per foot, meaning each foot of this beam weighs 15 pounds. None of the options provided in the question a) through d) correctly describe the meaning of the identification W8X15.
