Using the "eye and hand" method (i.e., method based on the physical visualization of the problem with the right-hand rule), find the moments about the $$x$$ axis $$\left({\stackrel{?}{M}}_x=M_x\vec{i}\right)$$, the $$y$$ axis $$\left({\vec{M}}_y=M_y\overrightarrow{?}\right)$$, and the $$z$$ axis $$\left({\vec{M}}_z=M_z\vec{k}\right)$$. Present a sketch showing $${\vec{M}}_x,{\vec{M}}_y$$, and $${\vec{M}}_z$$, using double-headed arrows. Note there are four forces applied.
