1. The problem statement, all variables and given/known data "A picture is supported vertically by a wire that is looped over a horizontal light peg P. There is no friction between the wire and the peg." (Please refer to the image attached) How would the free body diagram of the forces acting on the peg look like? 2. Relevant equations None 3. The attempt at a solution I know there's two forces along the wire coming out from the peg, but how about the upward forces? What provides the upward force to keep the peg in equilibrium?
