Answer :
The identification "W8x15" for a steel beam provides specific information about its dimensions and weight. Here's how you can understand what these numbers and letters mean:
1. W: This letter indicates that the beam is a wide-flange beam. Wide-flange beams are commonly used in construction and have a specific shape designed to support loads efficiently.
2. 8: This number represents the nominal depth of the beam in inches. In this case, the beam is approximately 8 inches deep.
3. 15: This number specifies the weight of the beam in pounds per linear foot. So, the beam weighs 15 pounds for every foot of its length.
Given this explanation:
- Option A is correct: the beam is 8 inches deep and weighs 15 pounds per linear foot.
Therefore, the correct answer to the question is option A.
