**drwls**, Monday, November 9, 2009 at 10:30amThe man closest to the center of gravity must lift 2/3 of the pole's weight. The other guy lifts 1/3 of the weight. You can prove that with a moment balance.

The pole's total weight is 115 x 9.8 Newtons.

You take it from there

**Philip**, Thursday, November 11, 2010 at 10:05amUse the formula for center of mass.

(∑ distance * mass) / total mass = center of mass

The masses are what each man is holding, the distance is where each man is from some origin. If you set the origin on one of the men, his distance * mass is 0. Since we know the center of mass is 6, we can solve for the mass. 2/3 for the man on the right and 1/3 for the man on the left.
