Assertion (A): A tapered wing box carries less web shear than a prismatic analysis suggests.

Reason (R): The inclined spar caps have transverse components that relieve part of the shear.

Select the correct answer from the options below.

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

Answer: D

Both are true and the second explains the first. The relief can amount to a significant fraction near the root where the caps are most heavily loaded, so treating a tapered box as prismatic is conservative but wasteful.
