A steel rod of sectional area 250 sq. mm connects two parallel walls 5 m apart. The nuts at the ends were tightened when the rod was heated to 100°C. If αsteel = 0.000012/C°, Esteel = 0.2 MN/mm2, the tensile force developed at a temperature of 50°C, is

80 N/mm2
100 N/mm2
120 N/mm2
150 N/mm2

Correct Answer: 120 N/mm2
