Problem
A mechanic uses a spanner of length 20cm to loosen a nut. He pulls perpendicular to the handle with a force of 25N at the extreme end of the spanner.
(a) Calculate the magnitude of the turning moment produced about the centre of the nut. Give your answer in SI units.
(b) State whether the turning moment is clockwise or counter-clockwise when viewed from the side where the force is applied.
