Question: The shortest configuration of string joining three given points is the one shown at the top of Fig, where all three angles are 120o.17 Explain

The shortest configuration of string joining three given points is the one shown at the top of Fig, where all three angles are 120o.17 Explain how you could experimentally prove this fact by cutting three holes in a table and making use of three equal masses attached to the ends of strings (the other ends of which are connected), as shown inFig. 120 120 120
