🤓 Based on our data, we think this question is relevant for Professor Nale's class at BU.

Solution: Three hollow metal rods, of equal length and negligible mass, are connected by pins to form an triangular frame as shown. The frame stands upright, and a weight is hung from the vertex of the triangle frame. What is the tension in the horizontal rod which forms the base of the triangular frame? 1. 135.1 2. 140.585 3. 72.1688 4. 102.768 5. 156.173 6. 76.4989 7. 187.061 8. 153.864 9. 168.009 10. 121.821
