Simple Volume Integral, limits of integration

Click For Summary
The discussion revolves around the correct limits of integration for a volume integral. The proposed limits are y from 0 to 2, z from 0 to 2, and x from 0 to 4 - z^2 for each z. There is a suggestion that changing the order of integration could yield the same result. The participants are focused on confirming the validity of these limits and the equivalence of different integration orders. Ultimately, the accuracy of the limits and the order of integration are central to achieving the correct answer.

Are my limits of integration right?

I would have done the integral in a different order. Obviously y will go from 0 to 2, z from 0 to 2, and, for each z, x from 0 to 4- z^2.

That should give the same answer, right?
 
Question: A clock's minute hand has length 4 and its hour hand has length 3. What is the distance between the tips at the moment when it is increasing most rapidly?(Putnam Exam Question) Answer: Making assumption that both the hands moves at constant angular velocities, the answer is ## \sqrt{7} .## But don't you think this assumption is somewhat doubtful and wrong?
