$1.$ Make a $3$D drawing with the position of the$3$ points using $1$ cm $=1$ft$.$ Add the vectorforces using $1$ cm $=100$ lb$\mathrm{.}2.$ Find FBa in cartesian notation form$\mathrm{.}3.$ Find FBc in cartesian notation form$\mathrm{.}4.$ Find Fr$,$ the resultant force in cartesian notation form, magnitude, and direction $($the angles a$,$ B$,$ y with x$,$ y$,$ and z axes respectively$)\mathrm{.}5.$ Draw Fr and its directions on the drawing$\mathrm{.}6.$ Find the angle between FBa and FBc and add it to the figure. Check that it makes sense
