Ok ignore the first 2 questions as I've already done em.

its just the rest i cannot figure out. If anyone could just shed a little light on this problem it i can finally sleep.

Thanks in advanced

oh btw the coefficient of thermal expansion tables is 3.2X10 to the power of -6 and steel 11x10 to the power of -6

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
