Question

tan (0) = height/length - 24 inches/28 inches
tan(0)=24/288=1/12
0=tan -1 (1/12)
0 = 4.76
height of the door abouve ground level is 24 inches
ramp angle : 4.76 degrees
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 design

Answer 1

To create a side view scale drawing of your wheelchair ramp based on the information provided, you will need to follow these steps:

### Materials Needed:
- Graph paper
- Ruler
- Pencil
- Protractor

### Step-by-Step Instructions:

1. **Setting the Scale**:
- Decide on a scale for your drawing (e.g., 1 square on the graph paper could represent 1 inch). This will help in accurately representing the dimensions of the ramp.

2. **Drawing the Height**:
- Since the height of the entrance is 24 inches, mark this height on the vertical axis of your graph paper. Count up 24 squares from the ground level (starting line) to represent the height of the door.

3. **Calculating the Ramp’s Length**:
- The horizontal length of the ramp can be calculated using the angle and height:
\[
\tan(\theta) = \frac{\text{height}}{\text{length}}
\]
with \(\theta = 4.76\) degrees. Rearranging gives:
\[
\text{length} = \frac{\text{height}}{\tan(\theta)}
\]
\[
\text{length} = \frac{24 \text{ inches}}{\tan(4.76^\circ)} \approx 288 \text{ inches}
\]

4. **Drawing the Ramp**:
- From the top point (24 inches up), measure out the length of the ramp (288 inches) horizontally to the right from this point. Depending on your scale, this could extend out to 288 squares if using a 1-inch=1-square scale.

5. **Connecting Points**:
- Draw a straight line from the ground level (the left side) to the top of the ramp (24 inches up on the right side), creating a ramp slope.

6. **Labeling**:
- Clearly label the height (24 inches) and the length of the ramp (288 inches). You might also want to label the angle of the ramp (4.76 degrees) next to the ramp line.

7. **Additional Details**:
- Optionally, you can add details such as the landing area at the top of the ramp and any side supports you might intend for the ramp structure.

### Example Layout:
- The vertical line represents the height of the door (24 inches).
- The horizontal base represents the ground (0 inches).
- The sloped line represents the ramp itself, connecting the ground to the door height at an angle of 4.76 degrees.

### Conclusion:
Once you have completed the drawing, double-check for accuracy in your measurements based on the scale you chose, ensuring that the ramp looks realistic and functions appropriately for wheelchair access.
