Question

If F1 = 103 N , F2 = 130 N and F3 = 90 N, determine the magnitude and coordinate direction angles of the resultant couple moment. (Figure 1)

Note that the figure is a 2-D perspective drawing of a 3-D object. As the dimensions in the figure indicate, the top part of the piping system is NOT parallel to the x-axis, rather it lies in an xy-plane and thus does not have a z-component. Also note that since F4 and −F4 are parallel to the z-axis, that couple cannot have a z-component, but does have both x- and y-components

Answer 1

I hope you understood the problem and got your answers, If yes rate me!! or else comment for a better solutions
