ADA Ramps

Decent Essays
Building codes change yearly on what things are sustainable. According to the Americans with Disabilities Act "The least possible slope shall be used for any ramp. The maximum slope of a ramp in new construction shall be 1:12" (Department of Justice ADA Title III Regulation 28 CFR Part 36, 1991) this comes out to be 4.8 degrees. In this lab we are going to analyze if a ramp at Grafton High School is ADA (Americans with Disabilities Act) objective. Our hypothesis is that since the Americans With Disabilities act was passed in 1990 then the ramp is would not be up to code, because it was built before the act was put into action. Here are a few keywords that you may need to know.

Angle of Elevation is the angle above the horizontal that

We did this by measuring the length of the whole ramp, width of the bricks, and height of the nine and seven eights bricks the above the wall base . Our results concluded that the ramp was at a legal slope. The length of the ramp was seven hundred and seventy- five inches, the width of the brick was seventeen over eight inches, and the wall base was four inches and the height of the wall was nine inches of full blocks and seven over eight inches of another block. If you were to find the height of the wall you would multiply nine inches by seven over eight inches which would give you twenty inches and then you would subtract twenty inches by four inches which would give you sixteen inches overall. To find the angle you would use Sin inverse, which would be sixteen(opposite) over seven hundred and seventy-five (hypotenuse) and the overall answer would be one point eighteen degrees for the angle. The angle of elevation is parallel line the alternating interior angles are congruent to the angle of depression so they would be the same (one point eighteen degrees). Summarizing the conclusion, though the results could have been more accurate, we see that the ramp is still legally designed for a hand-propelled
