Question

13. The aspect ratio of a hand glider describes its performance during flight. The formula R= gives the aspect ratio, R. for a hand glider with wingspan s and wing area A. [5 marks] a) Rearrange the formula to isolates. Use an arrow diagram to show the inverse operations you can use. b) Jack wants to design a hand glider with an aspect ratio of 2.7 and a wing area of 30 square feet What will be the wingspan of the gliders

Answer 1

13. for a hand glider with wingspan s and wing area A, the aspect ratio formula مل R= 52 A --- a) We know that as ad=bc Now R S А RA= = 1.5 7 RA=52 (since. s²=RA ☆s=FRÁ c/o) - a = so, s=JRA * 6 for this problem, R = 2.7 , A= 30 sqft then from the formula ①, we have s=TRA -5217x30 181 = 9 = 9 9 I feet. SO the wingspan of the glider will
