7 A rod of length 1000 mm and coefficient of linear expansion a 104 C is placed symmetrically between two fixed supports separated by 1001 mm The Young s modulus of the rod is 10 N m If the temperature is increased by 20 C then the stress developed in the rod is 1000 mm 1001 mm 1 10 N m 3 10 N m 2 10 N m 4 10 N m
