Rotational Inertia for Common Shapes Solid cylinder or disc, symmetry axis Rod about center Hoop about symmetry axis Solid sphere 1 I=-MR 1 = 1 = 5ML X 1 = {MR? 1= TM 1 = - MR 1 = MR2 = = ML? Hoop about diameter Thin spherical shell Rod about end *A uniform disk is mounted horizontally on a spindle so that it can rotate freely. The disk is initially at rest. A top view is shown. There are two exhaust ports which provide thrust when the engines are engaged. One is mounted 2m above the axel and the exhaust gases escape towards the right side of the page. The other is mounted 1 meter to the right of the axel and the exhaust gases escape towards the top of the page. Each exhaust port provides 20N of thrust. Ry=2m Ri=1m R=3m What is the magnitude of the angular momentum of the disk after the engines have engaged for 5 seconds? 20 kg m2/s 200 kg m2/s 100 kg ml/s O 30 kg m2/s 300 kg m2/s O 10 kg m2/s
