I have been given the following problem in one of my courses. To say that I'm struggling in the course would be an understatement... I'm just wondering what the difference between shear flow and stress is, wouldn't they be the same in each secion?
Consider the thin-walled section shown below. The section is fixed on one end, and an axial moment (T=12 kNm) is applied to the free end. The section is 6.9 m long. Do the following:
- Determine the shear flow in each section.
- What is the maximum shear stress in the section.
- Determine the angle of rotation of the free end (G = 26 GPa).
