Determine the corrections or otherwise of the following assertion and reason : Assertion : In general, wing twist should not be more than 6°. Reason: Wing twist is used to improve stall properties at tip. and are true and is the correct reason for b) Both and are true but is not the correct reason for c) is true but is false d) is false but is true Correct Answer A

Wing twist can optimize the wing lift at a particular lift coefficient. At any different lift coefficient wing twist will not provide 100% accuracy. Wing twist is also used to improve stall at tip.
