The hands of the clock in the famous Parliament Clock Tower in London are 2.7 m and 4.5 m long and have masses of 60.0 kg. and 100.0 kg respectively. Calculate the torque around the center of the clock due to the weight of these hands at 5:20. The weight of each hand acts at the center of the mass (the midpoint of the hand). I have the answer of -2200 N.m but cannot figure out how this was calculated.
