Two prismatic bars are rigidly fastened together and support a vertical load of 45 kN, as shown in Fig. 1-12. The upper bar is steel having length 10 m and cross-sectional area 60 cm². The lower bar is brass having length 6 m and cross-sectional area 50 cm². For steel E = 200 GPa, for brass E 100 GPa. Determine the maximum stress in each material. A A 10 m B B C 6 m 45 kN
