Two solid bars support a load P as shown. Bar (1) has a cross-sectional area of A₁ = 4000 mm² and an allowable normal stress of 155 MPa. Bar (2) has a cross-sectional area of A2 = 3650 mm² and an allowable normal stress of 85 MPa. Assume x₁ = 2.3 m, x2 = 3.6 m, y₁ = 0.8 m, and y₂ = 2.8 m. Determine the maximum load Pmax that can be supported by the structure without exceeding either allowable normal stress.
