**Question:** What are the nominal and actual depths of a W14x730 wide-flange member? Compare these to the nominal and actual depths of a W14x145. **Explanation:** This question focuses on understanding the differences between nominal and actual depths for different wide-flange steel beam specifications. Wide-flange beams are commonly used in structural engineering for their high strength-to-weight ratio and versatility in construction projects. 1. **Nominal Depth** - Indicates the "name" or designation of the beam size, usually based on its approximate height in inches. 2. **Actual Depth** - Refers to the precise measurement of the beam's height. **Example Members:** - **W14x730** indicates a nominal size designation where "14" represents the nominal depth and "730" is the weight in pounds per foot. The actual depth may vary slightly based on manufacturing standards and tolerances. - **W14x145** follows the same naming convention, with "14" representing the nominal depth and "145" as the weight in pounds per foot. For precise structural design and analysis, engineers must use actual depth measurements as provided in detailed engineering tables or standards, such as those from AISC (American Institute of Steel Construction).

**Question:** What are the nominal and actual depths of a W14 x 730 wide-flange member? Compare these to the nominal and actual depths of a W14 x 145. **Explanation:** This question pertains to the study of structural engineering, specifically the properties of wide-flange steel beams. Wide-flange beams are commonly designated by their nominal depth (in inches) followed by their weight per foot (in pounds). For instance: - **W14 x 730**: This designation indicates a nominal depth of approximately 14 inches and a weight of 730 pounds per foot. - **W14 x 145**: This indicates the same nominal depth but a weight of 145 pounds per foot. The nominal depth is an approximate measurement, and the actual depth can vary slightly based on manufacturing processes. Engineers must refer to structural steel tables or manufacturer specifications to find the exact dimensions. **Instructions:** 1. Look up the standard dimensions for W14 x 730 and W14 x 145 in a structural steel dimension table or reference. 2. Compare these actual dimensions to understand the differences in depth and cross-sectional size, despite similar nominal depths. This comparison is crucial in engineering to ensure that the selected beam can support the intended loads safely and efficiently.
