You and your friends are on an archaeological adventure and are trying to disarm an ancient trap to do so you
need to pull a log straight out of a hole in a wall. You have 1 rope that you can attach to the log and there are
currently 2 other ropes and weights attached to the end of the log. You
know the force and direction of the ropes currently attached are arranged
as shown below what is the magnitude and direction 'e' of the minimum
force you need to apply to the third rope for the force on the log to be in
direction of line 'a'? What is the resultant force in direction 'a'?
