Question 1
In thin-walled section analysis, what does shear flow $q$ represent?
Question 2
For a single-cell closed thin-walled section in pure torsion, which expression gives the constant shear flow?
Question 3
Why is a cut often introduced when analyzing a closed thin-walled section for shear flow?
Question 4
In the torsion formula $q=\frac{T}{2A_m}$, what does $A_m$ denote?
Question 5
What is a common feature of shear flow in a closed section under transverse shear?
