Question

Alberto wants to make a scale model of the Wright brothers' glider.
a. The wingspan of the scale model must be between 15 cm and 18 cm. What scale factor should
he use? Explain.
b. Using the scale factor from part a, what will be the length and height of the model glider?
c. Assuming the wings are rectangles, what will be the wing area of the model glider? If both wing
sections are the same size, what will be the dimensions of each wing section?
Wing Area:
28.3 m2
Wingspan: 9.8 m
Length: 4.9 m
a. What scale factor should he use? Select the correct answer below and fill in the answer box to complete your choice,
(Type an integer or decimal rounded to the nearest tenth as needed.)
O A. He should use a scale factor of . so the wingspan of the model is
ст.
O B. He should use a scale factor of 60, so the wingspan of the model is cm.
OC. He should use a scale factor of 80, so the wingspan of the model is cm.
O D. He should use a scale factor of 0. so the wingspan of the model is cm.

Expert Solution

Step 1

Given : Wingspan of the Wright Brothers model ( call it old ws )= 9.8 m

We need to scale the model in such a way that the new wingspan ( call it new ws) lies between 15 cm to 18 cm

So , it is better to convert old ws into centimetres ( simply multiply 9.8 X 100)

therefore old ws ( in cm) = 980 cm

As new ws should lie between 15 cm to 18 cm , option B and option C are incorrect as they will increase the wing span further where as we need to reduce it .
