MCQ · 2 Marks
Aerospace Structures • Thin-Walled Structures • Shear Flow in Multi-Boom Beams
In thin-walled structural analysis with boom idealization, the rate of change of shear flow along a skin panel between two adjacent booms 1 and 2 is determined by:
(A) The change in direct (axial) load carried by the boom: \Delta q = - \Delta P / \Delta s
(B) The atmospheric density outside the skin
(C) The shear modulus alone
(D) Thermal conductivity
Answer Key:
A
Step-by-Step Verified Solution
### Solution: From axial equilibrium of an idealized boom, the step change in shear flow across a boom equals the axial gradient of the direct load in that boom: q_2 - q_1 = - dP / dz. Correct: A.
