1. The problem statement, all variables and given/known data
A cylinder has a height and length of 0.89m. It's mass is known to be 1000kg. The cylinder is rotated at 14000 RPM. Calculate the Maximum stress in the cylinder. 2. The attempt at a solution The maximum stress should occur at the center of the cylinder. The centepietal force is equal to F=mv^{2} / r . Now this is where i'm having problems. After I calculate the force what area should I divide it by to find the max stress?. Can I just assume the area to be really small such as 0.001*d ?
