Problem Description

We are given a problem where an escalator is to be designed to make an angle of $$29^{\circ}$$ with the floor and carry people a vertical distance of 22 feet. The goal is to determine the length of the escalator required to achieve this.

Diagram of the Situation

Here is a diagram of the situation with all the given information labeled:

  +---------------+
  |  Escalator  |
  |  (Length = x) |
  +---------------+
           |
           |  Angle: 29°
           v
  +---------------+
  |  Vertical    |
  |  Distance: 22 |
  |  feet        |
  +---------------+

Given Information

Angle of the escalator with the floor: $$29^{\circ}$$
Vertical distance to be covered: 22 feet

Unknown Quantity

Length of the escalator: x

Mathematical Model

To solve this problem, we can use trigonometry. Specifically, we can use the sine function to relate the angle, vertical distance, and length of the escalator.

\sin(29^{\circ}) = \frac{22}{x}

Solution

To solve for x, we can rearrange the equation to isolate x:

x = \frac{22}{\sin(29^{\circ})}

Calculating the Length of the Escalator

Using a calculator to evaluate the sine function, we get:

\sin(29^{\circ}) \approx 0.484

Now, we can plug this value into the equation to solve for x:

x = \frac{22}{0.484} \approx 45.45

Conclusion

Therefore, the length of the escalator required to make an angle of $$29^{\circ}$$ with the floor and carry people a vertical distance of 22 feet is approximately 45.45 feet.

Discussion and Implications

This problem illustrates the importance of trigonometry in real-world applications, such as designing escalators and other mechanical systems. The use of the sine function allows us to relate the angle, vertical distance, and length of the escalator, making it possible to calculate the required length.

Future Work

In future work, we could explore other applications of trigonometry in engineering and design, such as calculating the height of buildings or the length of bridges.
