A uniform beam of length 7.60 m and weight 3.90 102 N is carried by two workers, Sam and Joe,
Sam=1.00m
Joe=2.00m
between both Joe and Sam there is 7.60m

(a) Determine the forces that each person exerts on the beam.
F_Sam = N
F_Joe = N

(b) Qualitatively, how would the answers change if Sam moved closer to the midpoint?

(c) What would happen if Sam moved beyond the midpoint?

It is not clear from your question what the two distance measurements mean.

Since Sam and Joe are 7.6 m apart, they must be at the ends of the beam

In any case, the problem can be solved by setting the total moment about any point equal to zero. The weight of the beam can be considered to be applied at the middle.
