Typo on Q5: Ansatz should be $e^{i\Omega t}$ (missing $i$).
By request, here is a simple explanation of how to prove the Cauchy stress theorem.
Typos and additions (Fri. May 3): For Q2, you can ignore body forces. For Q3, the solution in part d should have \[ -F_1 = -\mu \frac{U}{L} \left( \sqrt{\text{Re}} \pd{u}{Y} + \frac{1}{\sqrt{\text{Re}}}\pd{v}{x}\right) \]
(Note the Reynolds number factors are slightly changed)
During the 2009-2010 Trinity term, Oxford students made a valiant attempt to complete every single question of the last twenty years of B6a exams. Each filled square corresponds to a student successfully answering one of the problems.
Note: The material below was prepared prior to the 2009-2010 year. It has not been updated since then.
