Consider (Figure 1). Assume $(M_A)_x = 500$ lb$\cdot$ft, $(M_A)_y = 350$ lb$\cdot$ft, and $(M_A)_z = 350$ lb$\cdot$ft.
Determine the resultant couple moment acting on the pipe assembly.
Enter the $x$, $y$, and $z$ components of the resultant couple moment separated by commas. Express your answers in pound-feet to three significant figures.
