1) (a) If a rod of 1025 steel 19.7 in. long is heated from 68 to 176ï?°F while its ends remain fixed, determine the type and magnitude of stress that develops. Assume that at 68ï?°F the rod is stress free.

(b) What will be the stress magnitude if a rod 39.4 in. long is used?

(d) What is the magnitude of the stress in part (a) if only one end of the rod is fixed?
