if I want a ramp with a 30 foot length, and a 5 percent up grade starting at 0, how high will the tall end be?
To determine the height of the tall end of the ramp, you need to calculate the vertical rise or elevation gained over the 30-foot length. The 5 percent upgrade represents the ratio of the rise in height to the horizontal distance traveled.
To calculate the vertical rise, you can use the following formula:
Vertical rise = (Horizontal distance traveled) * (Gradient as a decimal)
In this case, the horizontal distance traveled is 30 feet, and the gradient is 5 percent or 0.05.
Vertical rise = 30 feet * 0.05
Vertical rise = 1.5 feet
Therefore, the tall end of the ramp will be 1.5 feet higher than the starting point.
