What is the calculated fall over a distance of 1200 mm with a slope of 1:10?

To determine the calculated fall over a distance of 1200 mm with a slope of 1:10, you first need to understand how slope works in this context. A slope of 1:10 means that for every 10 units of horizontal distance, there is a rise or fall of 1 unit.

Given a horizontal distance of 1200 mm, you can calculate the vertical fall by applying the slope factor. The method involves dividing the horizontal distance by the slope ratio, which in this case is 10.

By performing the calculation:

1. Calculate the fall:

Fall = Horizontal distance / Slope ratio

Fall = 1200 mm / 10

Fall = 120 mm

Therefore, the calculated vertical fall over a distance of 1200 mm at a slope of 1:10 is 120 mm. This confirms that the correct answer is indeed accurate based on the principles of geometry and slope calculations used in carpentry.
