At what angle does the coefficient of lift over a flat plate become maximum?(a) 66.6 deg(b) 54.7 deg(c) 33.3 deg(d) 90 degI got this question by my college director while I was bunking the class.My question is from Time-Marching Technique topic in portion Time-Marching Technique of Aerodynamics

Answer» RIGHT answer is (B) 54.7 deg

The best explanation: According to the Newton’s theory, the coefficient of LIFT is given by:

cl = 2sin^3α

This VALUE is maximum for α = 54.7 DEGREES.
