how do i find the vector AC in this problem? the terms i j k$.$ EXERCISE $1\mathrm{.}1$ The rectangular plate is welded at comer $A$ to the

vertical shaft and braced by cable $BC.$ The tension in the cable is $5$

kN $.($a$)$ Determine the components parallel to the edges of the plate of

the force the cable applies to the plate. $($b$)$ Determine the moment

about corner $A$ of the force applied by the cable. $($c$)$ Determine the

moment about the axis of the shaft of the force applied by the cable.

$($Hint: Use $A$ as the origin of frame $xyz.$ The direction of $y$ is from $A$ to

B$.x$ direction is along another edge of the plate. $z$ direction is perpendicular to the plate

upward.$)$

What is the vector AC in this problem in terms of i$,$ j $,$ k components. see $2$nd image red arrow indicating AC and coordinate system xyz layed out in the image as well.
