Groupwork 5 (Due Date: Friday October 03, 2025)
Q1) A 77-N force F1 and a 31-N m couple M1 are applied to corner E of the bent plate shown. If
F1 and M1 are to be replaced with an equivalent force-couple system (F2, M2) at corner B and if
(M2)z = 0, determine (a) the distance d, (b) F2 and M2.

Q2) A 110-N force acting in a vertical plane parallel to the yz-plane is applied to the 220-mm-long
horizontal handle AB of a socket wrench. Replace the force with an equivalent forcecouple system
at the origin O of the coordinate system.

Q3) If P = 0, replace the two remaining couples with a single equivalent couple, specifying its
magnitude and the direction of its axis.
