B. On a separate sheet of paper, provide a rough sketch of the ramp or ramp sections with labeled horizontal run, vertical rise, ramp length, and angle that the ramp makes with the ground. Below your sketch, include the calculations you made to determine the horizontal run and vertical rise of your ramp. Round all final answers to the nearest tenth. Day 2 In Day 1, you designed a wheelchair ramp for an entrance that is between 12 and 30 inches above ground level. Now, you will create a side view scale drawing of your ramp as you practice communicating clearly. Do the following: A. On a separate sheet of graph paper, create a side view scale drawing of the ramp you designed in Day 1. Neatly label all side lengths and angle measurements. Imagine that you are submitting your design to a town committee that will need to approve your design before construction can begin. The committee needs to both understand your design and feel confident that it follows ADA guidelines. Do the following: B. Describe your ramp and the dimensions of your ramp in words, as clearly as possible.

Answer 1

Day 1: Ramp Design and Calculation

Ramp Sections Sketch:

(As I cannot generate images, I will describe how you should structure it)

1. Draw a right triangle to represent your ramp.
2. Label the horizontal base as "Horizontal Run".
3. Label the vertical side as "Vertical Rise".
4. Label the hypotenuse (the ramp itself) as "Ramp Length".
5. Label the angle between the ground and the ramp as "Angle of Incline".

Example Calculations:

Assume the booth is 24 inches (2 feet) above ground level (Vertical Rise) and you want to create an ADA-compliant ramp with a slope of 1:12.

1. Vertical Rise (VR) = 24 inches

2. To find the Horizontal Run (HR): \[ \text{HR} = \text{VR} \times 12 = 24 , \text{inches} \times 12 = 288 , \text{inches} , \text{(or 24 feet)} \]

3. Calculate Ramp Length (RL) using the Pythagorean theorem: \[ \text{RL} = \sqrt{(\text{HR})^2 + (\text{VR})^2} = \sqrt{(288)^2 + (24)^2} = \sqrt{82944 + 576} = \sqrt{83520} \approx 288.7 , \text{inches} , \text{(or 24.0 feet)} \]

4. Calculate the Angle of Incline (θ): \[ \theta = \tan^{-1}\left(\frac{\text{VR}}{\text{HR}}\right) = \tan^{-1}\left(\frac{24}{288}\right) \approx \tan^{-1}(0.0833) \approx 4.76^\circ \]

Day 2: Scale Drawing and Description

A. Side View Scale Drawing:

• Create the triangle with the following lengths:
  • Vertical Rise (VR): 24 inches
  • Horizontal Run (HR): 288 inches
  • Ramp Length (RL): approximately 288.7 inches, rounding this to 288 inches for simplicity may also be done for scale purposes.
• Label the drawn triangle with all the dimensions: VR, HR, RL, and the angle of incline.

B. Ramp Description:

The wheelchair ramp is designed to allow access to a structure that is elevated 24 inches above ground level. The ramp has a gentle slope that adheres to the Americans with Disabilities Act (ADA) guidelines, which recommend a 1:12 slope for wheelchair accessibility. This design calls for a horizontal run of 288 inches (24 feet) and a vertical rise of 24 inches. The length of the ramp measures approximately 288.7 inches, providing a smooth transition for individuals using mobility devices without risking excessive strain or safety concerns.

The angle of incline at which the ramp rises is approximately 4.76 degrees, ensuring a comfortable ascent. The drawing accurately represents these dimensions and adheres to the necessary standards for safety and accessibility. The structure's compliance with ADA guidelines assures that it will be safe and usable for all individuals.

This detailed description and structured sketch will facilitate the approval process with the town committee by clearly conveying the essential aspects of the ramp design.
