Three men 4, apart are carrying a heavy load on a pole. Two are one end of the pole and the third is at the other end. Where should the load be placed so that each man gives equal support?

1. what does three men 4 mean?

2. oh sorry, 4 meters apart, I mean.

3. Pick an end and sum moments:
I will start at the two men end.

W*L-F*4=0
Now if each is "shouldering" and equal weight, then F=W/3
put that in the equation and solve for L, the length for the weight from the two men end.

4. oh, ok, I see; i had thouht of something along those lines, but was thrown off by seeing two variables, but now I see how that can be done; thank you!
