The rigid body OAB includes a vertical member, OA, that is 0.3m long and a horizontal member, AB, that is 1.9m long. AB is located in a plane parallel to the XZ coordinate plane, and forms a 50 angle with the XY plane. A cable at B creates a 625N force that acts along BC. C is located in the XZ plane at x= 0.4m and z = 1.2m. Equal, but opposing 540N forces are aligned to the x-axis and act at O and B. At A, a force, F = -120i + 56j + 150k N, is applied. Generate the equivalent force couple at A. Use vector notation to describe both the force and the couple. (NOTE: vector lengths and angles not to scale) F = -120i + 56j + 150k N ZA 0.3m 540N C A 50 625N 1.9m B X 540N
