A steel beam that is 7.00 m long weighs 352 N. It rests on two supports, 3.00 m apart, with equal amounts of the beam extending from each end. Suki, who weighs 595 N, stands on the beam in the center and then walks toward one end. How close to the end can she come before the beam begins to tip?

Answer 1

the beam weight is 50.3 N/m

when Suki crosses a support to some distance (d), the equilibrium equation is
... (100.6 N * 1.00 m) + (595 N * d)
... = (251 N * 2.50 m)

the distance from the end is
... 2.00 m - d
