Rigid bar BC is supported by aluminum rod (1) and bronze rod (2), as shown in the figure. Aluminum rod (1) has a diameter of 10 mm and a cross-sectional area of A1 = 78.54 mm2. The stress in rod (1) may not exceed 170 MPa. Bronze rod (2) has a diameter of 13 mm and a cross-sectional area of A2 = 132.73 mm2. The stress in rod (2) may not exceed 110 MPa. Assume that L = 1900 mm and a = 900 mm. Determine the largest load magnitude P (in kN rounded to the nearest tenths) that may be applied to rigid bar BC.
