(a) A rod of steel 0.5 m long is heated from 20 C to 80 C while its ends are maintained rigid. Determine the type and magnitude of the stress that develops. Assume that at 20 C the rod is stress free. E(steel)=207GPa thermal expansion=13*10^-6/C

(b) what will be the stress magnitude if a rod 1 m long is used?

(c) if the rod in part (a) is cooled from 20 C to - 10 C what type and magnitude of stress will result?
