1.	The cross section of a compound bar 1 m long is as shown in figure. If the temperature is raised by 80°C determined the stresses (in N/mm2) in each metalEss = 2 × 105 N/mm, Ec = 1 × 105 N/mm2, αc = 16 × 10-6/˚C, αs = 12 × 10-6/˚CAss = 600 mm2, Ac = 200 mm2
A.	σc = 20 (Compressive), σss = 30 (Tensile)
B.	σc = 30 (Compressive), σss = 20 (Tensile)
C.	σc = 30 (Tensile), σs = 20 (Compressive)
D.	σc = 30 (Tensile), σss = 20 (Compressive)
Answer» C. σc = 30 (Tensile), σs = 20 (Compressive)
