A huge vertical pump configuration, comprised of one solid disc A and two solid rotors B, is started from rest with a motor drive that delivers torque as a function of time. Determine (a) the total mass moment of inertia in kg-m^2, (b) the angular velocity in RPM 45 seconds after starting from rest and (c) the number of revolutions in that same time period. The mass and radius of disk A are 29800 kg and 2.8 m and same for one rotor B are 1100 kg and 0.3 m. The torque vs time function is: T = 8.4E4 t ^(0.35) N-m. B 29800 1100 2.8 0.3 8.4 0.35 45
