Replace the loading system by an equivalent resultant force and specify where the resultant’s line of action intersects the member AB measured from A.

Replace the three forces shown by an equivalent force-couple system at point A. If the forces are replaced by a single resultant force, determine the distance d below point A to its line of action. Answers: R = M = 280 N i 395 N d = i Force-couple system at A. The force is positive if to the right, and the couple is positive if counterclockwise. Single resultant force. 210 N 670 mm 670 mm 670 mm N N.m mm

Replace the three forces shown by an equivalent force-couple system at point A. If the forces are replaced by a single resultant force, determine the distance d below point A to its line of action. Answers: R= i M= i 160 N 290 N d = Single resultant force. i www Force-couple system at A. The force is positive if to the right, and the couple is positive if counterclockwise. 300 N 650 mm 650 mm 650 mm N N.m mm

Handle forces F1 and F2 are applied to the electric drill. Replace this force system by an equivalent resultant force and couple moment acting at point O. Express the results in Cartesian vector from. Determine the resultant force and the moment of the resultant forse about the point O. Express your answer in terms of the unit vectors i, j and k.
