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?
