Problem
A force F=6i−2j+5kN acts at a point whose position vector with respect to the origin is r=3i+4jm.
(i) Calculate the torque vector about the origin produced by this force.
(ii) Determine the numerical value of its magnitude.
(iii) State whether the torque tends to produce clockwise or counter-clockwise rotation about the z-axis.
