The top and bottom faces are subjected to equal tensle stresses of 15,000 psi (note the word Tensle). The front and back faces are subjected to equal compressive stresses of 20,000 psi (note the word compressive) The ends (4x2. dmension) are restrained from any movement in the x-drection. The block is
100% 9:42 PM 5 (10 points) A steel block has initial dimensions of 20x4x2. The top and bonom faces are subjected to equal tensle stresses of 15,000 psi (none the word Tensle). The front and back faces are subjected to equal compressive stresses of 20,000 psi (note the word-compressive). The ends (4-X2- dimension) are restrained from any movement in the x-direction The block is heated up such that AT= Warning: The strain caiculations yield small numbers so carry at least 6 decimal places in your calculator (a) (8 points) Determine the stress in the x-drection and the stains in the y and z directions. Part b) is on following page Problem 5-Continued
