A compound cylinder is formed by shrinking a tube of 200mm outside and 150mm inside diameter on to one of 150mm outside and 100mm inside diameter. Owing to shrinkage the radial stress at the common surface is 20 MN/m². If this cylinder is now subjected to an internal pressure of 100 MN/m², what is the magnitude and position of the maximum hoop stress?
n a Laboratory, you have the following chemicals available:
1.0 M NaOH, 1.00 M HCl, 1.00 M H3PO4, NaH2PO4 (s), Na2HPO4 (s), and Na3PO4 (s).
