Enrol to our Review Center: https://www.facebook.com/share/1AC24Wsb9v/?mibextid=wwXIf SITUATION: A hollow, circular, cast-iron pipe (Ec = 82 GPa) supports a brass rod (Eb = 96.5 GPa) and weight W = 8.9 kN, as shown. The outside diameter of the pipe is dc = 150 mm. Given: Unit weight of steel = 77 kN/m3 Unit weight of brass = 82 kN/m3 1. If the allowable compressive stress in the pipe is 35 MPa and the allowable shortening of the pipe is 0.5 mm, what is the minimum required wall thickness (mm)? A. 0.50 C. 0.02 B. 0.58 D. 0.54 2. What is the elongation (mm) of the brass rod due to both load W and its own weight? A. 0.8975 C. 0.9286 B. 0.8980 D. 1.1231 3. What is the minimum required clearance h, in mm? A. 1.50 C. 1.40 B. 1.52 D. 1.38 Thanks for watching! Comment for questions and suggestions for future lecture in this series.
