A 1.5 m long, 304 stainless steel rod is fixed to a wall at point A. Between the end of the rod and point B, there is a 1 mm gap. For 304 stainless steel, use =0.000017 1/C, E=193 GPa, and OY=207 MPa. A B L=1.5 m 1 mm gap a. Compute the normal stress in the rod if it is heated by 80 C b. Compute the necessary temperature rise to yield the rod c. Compute the temperature rise for the rod to touch the wall at point B without inducing a normal stress in the rod [10 points] [10 points] [5 points]
