I was doing a Compressible Flow ME3231 tutorial. Think of the
module as a zhnged-up version of Fluid Mech, and you'll get a rough
idea of what it's like.
I had spent 1 1/2 hours on what seemed like a killer question the
previous night before finally giving up in utter frustration.
Then just now, I looked at the question again. After staring at it
for a few minutes, the answer became clear to me all of a
sudden.
It took all of five minutes for me to work out the answer.
Basket.... I wasted so much time and effort last night for nothing.
