A landscaper tries to plumb a tree by applying a 240-N force as shown.

(a) Replace that force with an equivalent force-couple system at C.

(b) Two helpers attempt to plumb the same tree, with one applying a horizontal force at C and the other pulling at B. Determine these two forces if they are to be equivalent to the single force of part a.
