In the figure, a circular cross-section rod with a diameter of 4 cm, made of material with number 1, is placed inside the pipe produced from material with number 2. The entire system is mounted on a rigid plate from below and on a fixed wall from above. The temperature when the system is installed is 10C. How much should the temperature be changed to close the 0.0K cm gap? 100cm * 8cm cm 10m Section (2) 0.0K 1-16.1061/C Rigid Plate 2-12.1061/Co E1=100 GPa E2=200 GPa Oallow,1=100 MPa Gallow,2 150 MPa
