7. Make the radius of tube 2 thinner. In the tug of war between masses, who does this help? 8. Make the radius of tube 2 equal to the radius of tube 1. Which mass "won" when the radii were equal? 9. Make sure the radius of tube 1 is 46 mm and then see if you can find a radius for tube 2 that will keep the system in equilibrium when the pin is pulled out. What seemed to be the perfect radius ?( do not change value of Tube 1 through the experiment 10. Set the Mass 2 to 100I grams and the radius of Tube 2 to 24 mm. Pull the pin and see if Tube 2 is lifted by the 100 grams in Tube 1
