49. Justify the claim in Example 10 on page 756 that a Q. northropi weighing 200 lb with a wingspan of 50 ft would have had the same wing loading as one weighing 100 lb with a wingspan of 36 ft.
49.
The square of wingspan is proportional to wing area, so the wing loading is proportional to weight divided by square of wingspan. For the 200-pounder, that ratio is , while for the 100-pounder it is —close enough.
