E-020. Two axial members are used to support a load P applied at joint B. Member (1) has a cross- sectional area of 3,080 mm² and allowable normal stress of 180 MPa. Member (2) has a cross- sectional area of 4,650 mm² and allowable normal stress of 75 MPa. Determine the maximum load P that may be supported without exceeding either allowable normal stresses. 4.3 m 5.0 m (1) 2.0 m B P (2)
