Problem 7 only, solve carefully, include the units in every step and draw the diagram. Thanks!

8. What temperature will the rails just touched if steel railroad is 10 m long are laid with clearance of 3 mm at initial temperature of 15 C. Use k = 11.7 x 104 m/m C. Also compute the strain and stress. 9. A force tangent to 1 foot diameter pulley is 5 KN and is mounted on a 2 inches shaft. Determine the torsional deflection if G = 83 x 10 Kpa. 10.The pressure inside the cylindrical tank varies from 810 kpa to 3210 kpa continuously. The diameter of shell is 1.5 m. Find the following if yield point is 455 Mpa, endurance strength is 195 Mpa and factor of safety of 2.5. A. Wall thickness, mm B. The maximum stress C. The minimum stress
