1. The problem statement, all variables and given/known data A 5.0kg mass is suspended from the ceiling. A horizontal force F is applied to hold the string in position as shown http://i.imgur.com/ZdR72ff.jpg Determine the reading of F on the spring balance by using a scale diagram 2. Relevant equations None 3. The attempt at a solution http://i.imgur.com/2KO2AnT.jpg Am I doing it correctly? It doesn't really make sense to me. I can't determine the force F. I only have 30degree angle and the weight. I don't know how to draw the length of Force F. What is it should I be looking for? Thank you!
