Question

As shown, a member is fixed at the origin, point O. and has two applied forces. F1 and F2, applied at the free end. point B. (Figure 3) The forces are given by F1 = 90 N i = 130 N j + 65 N k and F2 has magnitude 175 N and direction angles alpha = 158.0 degree , beta = 77.0 degree , and gamma = 72.6 degree . The dimensions are x1 = 4.10 m, y1 = 5.80 m. and z1 = 2.85 m. What is the moment about the origin due to the applied forces? Express the individual components of the Cartesian vector to three significant figures, separated by commas.
