...way to learn. But being a student at a really tough university, I just dont have time for this. Physics is probably my least hardest class compared to the others. So I must work quick. If you must give hints, please give useful ones that dont require much give and take. Cedrics hints in previous questions were very helpful. Noldorin's hint was more complicated than the original question. Just dont be stingy/cocky..

PF hasnt really helped me. I'm a university student. I only have a certain amount of time to allocate to each subject before I have to move on to the next. The past few hours I dedicated to physics. I do my homework, and sometimes I have questions. I post a question on PF, and if I'm lucky, 3 hours later I'll have a response. Turns out, this response is not a hint, but only another puzzling question that I must ask myself. So I play the game. I answer the question/hint. Then they ask me another question, so that I may by myself eventually arrive at a conclusion. This is, no doubt, a great...

Honestly the thing is that although this is the right way to approach things to help the person learn, this process takes forever. A typical homework assignment (for me at least) has about 30 questions. If it takes me 15 minutes looking for answers to a simple unit question, then I will never finish my assignment. This is the reason I dont use physicsforum.com anymore. It takes HOURS to get a simple answer, and the answers they give are just 'hints', so by the time we give and take, 5 hours would have past, and I still have so many questions to go. I learn by example more than anything..

This is barely a homework question. Just a matter of units is all

Ya I was able to get the same thing from wolfram wolframalpha.com/input/?i=1.132+radians/second thanks though!

Ohh ok I see so I was using the total I instead of just I[rod]..answer is .209, thanks!

comment Angular Momentum and Average Torque
So does that mean that the answer I put in number 4 is incorrect? I multiplied the final angular velocity by the total moment of inertia of the system, which is .3023 and that multiplied by 26.03 is just 7.87

Wait so, I already have the answers for 1 and 2 (right?) So what am I missing?

comment Finding angular acceleration from torque
Hmm not really sure..so there is actually a way to get an actual value for this thats not in terms of L or R?
