Problem
A 2.8 kg bucket hangs vertically from the end of a horizontal rod 0.40 m long that is fixed to a wall at its other end. Taking g=9.8m s−2, calculate the magnitude of the torque about the wall due to the weight of the bucket. Express your answer in scientific notation to two significant figures.
