Final answer:
When sizing up a building, the top member looks at general proportions, spacing between columns, size and height of the building, and weight distribution. Math is used to calculate ratios and distances. Engineers must consider the weight difference at the top of a tall building and design proper structural support.
Step-by-step explanation:
The top member is looking for several factors when sizing up a building, including the general proportions, spacing between columns, and the size and height of the building. Math plays a key role in these calculations. For example, if the length and width of the building are expressed mathematically as X = Y x 2 + 1, then ratios can be used to compare the scale distance to the actual distance. Additionally, the engineer needs to consider the weight at the top of a tall building and how it compares to that on the first floor. This is important to ensure the structural support is designed correctly.
