If d = 6 ft, determine the resultant couple moment either by summing the moments of the two couples or resolving each force into x and y components and then summing the moments about B of all the force components. Express your answer in pound-feet to three significant figures. Enter positive value if the moment is counterclockwise and negative value if the moment is clockwise.
While cutting a piece of paper, a person exerts the two indicated forces on a paper cutter. Reduce the two forces to an equivalent force-couple system at corner O and then specify the coordinates of the point P in the x- y plane through which the resultant of the two forces passes.

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. M₁ 7m = 100 N·m 3 m 3 m 400 N 3 m SOTER 600 N
