Choosing the Second Rope

ID: k8gngyy2gc

Problem: A crate is dragged along the \(x\) axis by two ropes with a resultant of 1 kN along \(+x\). Rope A pulls at \(30^\circ\) above \(x\). In which direction should rope B pull so that its force is as small as possible? Find the forces in both ropes for that direction.
