1. The problem statement, all variables and given/known data Four rockets attached to a (wheel) space station exert a force of 65.5N to rotate it . The space station's angular velocity is increased at a constant acceleration of 3.63 x 10-3 rads-2. Each rocket is 11.2m away from the centre. Calculate the rotational inertia of the system. 2. Relevant equations τ=Iα , others unknown. 3. The attempt at a solution Torque of all 4 rockets. (65.5N * 11.2) * 4 = 2934.4N since τ=Iα, I=τ/α hence I= 2934.4/3.63x10-3 = 808374.7Kgm2 Can anyone confirm if this is the correct method. Thanks.
