Direct Stress and Strain

A steel rod having a cross-sectional area of 0.005m2 and length 3m is attached to supports. Find (a) the force exerted by the rod on the supports if the temperature falls 60 degress and the supports are unyielding. and (b) the force exerted by the rod on the supports if they yield 0.0002m while the temperature raises 50 degrees. Take E=210Gpa, coefficient of thermal expansion = 10.5x10-6 degrees-1
