Chapter 4, Problem 87P

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

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.

C. From the given coplanar force system which consists of two forces and one couple. Replace the force couple system with force acting at A. a.Determine the resultant force acting at point A. b. Determine the Angle that the resultant makes with the x-axis. c. Determine the x and y intercepts of the Resultant Force. d. Determine the resultant couple acting at point A.
