 P: 304 1. The problem statement, all variables and given/known data In procedure 3, you balance the ruler. If the density of the ruler increases without changing its dimensions, the ruler will... →still be balanced →be unbalanced, but the direction depends on the hanging mass, the mass of the ruler, and distances →tip away from m →tip toward m In my lab report, it says that I need to balance the ruler at the 40 cm mark and then, adjust the mass to the left to make the ruler balanced. 2. The attempt at a solution I said that the ruler will tip away from m, contrast to the ruler hung at the center 50 cm mark, but I'm not sure if that is true.
 P: 2,526 Replace the ruler with massless ruler and an equivalent mass hanging from its center of gravity.
 P: 355 The centre of gravity will not move to another point when its density is increased - look at the formula for calculating the coordinates of the centre of gravity - this is what CWatters suggests in effect just worded differently.
