A positively cambered airfoil with a zero-lift angle of attack of ?3has a lift slope of 0.1 per degree.

a. Calculate the lift coefficient at an angle of attack of 5

b. Now the same airfoil is turned upside-down (so it becomes an airfoil with a negative camber). Calculate its lift coefficient at the same angle of attack of 5 as in part a.

c. At what angle of attack must the upside-down airfoil be set to generate the same lift as that when it is right-side-up at a 5 angle of attack?
