    Calculating Angular Acceleration of Hollow Sphere with Pressure Difference

    Ohh, ok so the force would be, F = P*A F = 1.5*(pi*r^2) F = 0.00471 So now for torque: t = r * F t = (0.2m+0.1m) * 0.00471 t = 0.200047 Lastly sigma t = I*a a = sigma t/I a = 0.108025 OK this sounds like a more reasonable answer thanks for the help. Now I only need to...

    Calculating Angular Acceleration of Hollow Sphere with Pressure Difference

    Sorry for bringing this up again, but I can't find the force due to the pressures. Can someone tell me how to find it please, no need for a blunt answer, but a formula to use would do just as well? After this I am pretty sure I can finish the problem on my own.
