Two solid bars support a load P as shown. Bar (1) has a cross-sectional area of Al 4100 mm" m^2 and an allowable normal stress of 155 MPa. Bar (2) has a cross-sectional area of A2=3050 mm^2 and an allowable normal stress of 160 MPa. Assume xl=2.0 x2=2.7 y = 0.8 and m. Determine the maximum load Pmax that can be supported by the structure without exceeding either y2=3.4 allowable normal stress.
