A rod is 2m long is initially at a temperature of 10 degrees c. Find the expansion of the rod when the temperature is raised to 100 degrees c. If this expansion is prevented, find the stress induced in the material of the rod. Take E= 105kN\mm2 and co efficient of thermal expansion a= 1.2×10 raised to negative 5 per centigrade
