This is a straightforward calculation, with modest bookkeeping requirements, that is possible with undergraduate physics and calculus. As a sci-fi author, your craft will be improved by forcing yourself to do it. You'll be concerned with centripetal acceleration, yield stress, density, pressure, free body diagrams of pressure vessels, summation of forces on a differential element, and fairly basic integration (after taking symmetry into account).
