Final answer:
The 'The purlin should be the same size as the ridge' principle ensures the roof of a structure has proper support, which is crucial for the building's stability and longevity.
Step-by-step explanation:
The principle 'The purlin should be the same size as the ridge' impacts the construction of a structure by ensuring that the roof can evenly distribute the load imposed on it.
This principle ensures that structural support is appropriately designed and that the purlins (which are horizontal beams along the length of the roof), are capable of carrying the weight transferred to them from the roof covering materials all the way to the main structural framework.
This alignment of sizes helps maintain the balance and integrity of the structure, preventing potential collapse due to uneven weight distribution.
For a full understanding of how weight is distributed in structures, engineers must consider the value of gravitational pull (g) at different heights.
Although the change in g is very slight between the top of a tall building and the first floor, over significant distances, such as in very tall buildings, this can affect the total weight a structure supports.
While the difference is often negligible, in the design of structurally sophisticated constructions, these small variations can inform design choices.
