Been looking through my notes for a basis to start this question but can't seem to find a starting basis due to poor handouts (or more likely bad note taking by me)
Heres the question
A cocnave astronomical telescop mirror may be made by rotating a circular tank of mercury. Find an experssion for hte shape of the surface in terms of the density, distance from the center and rotation rate.
my initial thoughts are along the lines of when the 'internal resistance force' of the mercury is equal to the centripetal force required to keep it in place. But the problem lies in i have no clue how to calcuate this 'internal resistance force' of the mercury, any information you can offer would be appreciated
