The rigid bar of negligible weight is pinned at B and attached to two vertical rods at A and D. Assuming that the rods were Initially stress-free, what is the largest load P that can be applied without exceeding stresses of 150 MPa in the steel rod and 70 MPa in the bronze rod? Use a = 2m. b = 3.5 m andc =1.2 m, For steel. A = 800 mm?, L=2 m and E 200 GPa, For Bronze: A = 400 mm?, L= 1.5 mand E = B3 GPa b. Bronze Steel
