Assertion (A): A compression panel idealisation usually requires iteration.

Reason (R): The effective skin width depends on the stiffener stress, which itself depends on the effective area.

Select the correct answer from the options below.

  • A.Both A and R are true, and R is the correct explanation of A
  • B.Both A and R are true, but R is not the correct explanation of A
  • C.A is true but R is false
  • D.A is false but R is true

Answer: A

Correct answer: Both A and R are true, and R is the correct explanation of A

Both are true and the reason gives the circularity. The effective width depends on the stiffener stress, and the stiffener stress is the load divided by the effective area, which includes that effective width. Neither can be found without the other, so the calculation is begun with an assumed stress and repeated until the two agree - usually two or three passes are enough.
