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 γ = 77 kN/m3 and E = 200 GPa, for brass γ = 84 kN/m3 and E = 100 GPa. 1. Determine the maximum stress in steel bar. A. 9.50 MPa C. 10.12 MPa B. 8.69 MPa D. 12.56 MPa 2. Determine the elongation of steel. A. 0.54 mm C. 0.415 mm B. 0.375 mm D. 0.396 mm 3. Determine the total elongation of the bars. A. 0.970 mm C. 0.909 mm B. 0.989 mm D. 0.915 mm Thanks for watching!
