Determine the components of the moment about O of the force F acting on the assembly point A, if the turnbuckle is tightened until the tension in the cable AB is 2.4kN.
1. Given the two forces and a couple M₁ shown, find the equivalent force-couple system
acting at O. Then, replace the force-couple system with a wrench resultant, by writing the
force and the moment associated with the wrench in a Cartesian vector form. You can assume
that the point P through which the line of action of the wrench passes is already known and
do not need to be calculated.
