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 115 N i- 110 Nj+55 N k and F2 has magnitude 195 N and direction angles a = 143.0°, B= 57.0°, and y 75.2°. The dimensions are a1 = 1.30 m, y1 = 1.85 m, and z1 = 1.10 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.

F, F, F
point B.
(Figure 3)
Notice that the order of the elements of the matrix
determinant is important; switching rows 2 and 3 of the
determinant would change the sign of the moment from
positive to negative (or vice versa.)
The forces are given by F1 = 115 Ni- 110 Nj+ 55 N k and F2 has magnitude 195 N and direction angles
a = 143.0°, B= 57.0°, and y= 75.2°. The dimensions are x1 = 1.30 m, y1 = 1.85 m, and z1 = 1.10 m.
What is the moment about the origin due to the applied forces?
