A picture frame hung against a wall is suspended by two wires attached to its upper corners. If the two wires make the same angle with the vertical, what must this angle be if the tension in each wire is equal to 0.75 of the weight of the frame? (Ignore any friction between the wall and the picture frame.)
Solution 5E Step 1: This the vector components of tension and force acting on the photo frame. Since, we are hanging it on the two top corners, the resultant force acting downwards will be the weight of the photo frame, w = mg
