Im trying to build a set of ramps for a heavy duty truck to drive on. Im using 4" X 4" X 1/4 square tubing. the length is 12' and the height is 2' 6" with a 4' deck on top for the rear axles. I need to find the formula to achieve the correct angle for the incline. thank you in advance for any help.
