The corner of a tent is supported using three ropes having the forces shown. It is desired to compute the sum of the cross products  where  is the position vector from points O to A , is the force directed from points A to B ,and so on.

(a)    Rather than compute three separate cross products to find  , do the properties of the cross product permi to be found using just one cross product? Explain.

(b)   Determine
