all 2018 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. 5.0 m 2.0 m 4.3 m (1) 4 B P (2)
