The corner of a tent is supported using three ropes having the forces shown. We wish 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 fin , do the properties of the cross product permit to be found using just one cross product? Explain.

(b) Determine
