Equivalent forces
Three cables attached to a disk exert on it the forces shown.
(a) Replace the three forces with an equivalent force-couple system at A.
(b) Determine the single force which is equivalent to the force couple system obtained in part a, and specify its point of application on a line drawn through points A and D.

The steel plate shown will support six 50 mm diameter idler rollers mounted on the plate as shown. Two flat belts pass around the rollers, and rollers A and D will be adjusted so that the tension in each belt is 45 N. Determine
(a) the resultant couple acting on the plate if a = 0.2 m,
(b) The value of a so that the resultant couple acting on the plate is 54 Nm clockwise.
