A non-uniform bar weighs 400 N and is 4 m long. When it is supported by an fulcrum at its midpoint, a load of 80 N must be supplied at the smaller end to hold the bar in a horizontal position. Where is the center of gravity?

400x = 80(2)
x = 0.4 m from the fulcrum or 2 - 0.4 = 1.6 m from the larger end.
