1. (Source: Ph.D. qualifying exam, 1996) A laminated thick-walled hydraulic cylinder was fabricated by shrink-fitting jacket having an outside diameter of 300mm onto a SS 304 steel tube having an inside diameter of 100mm and an outside diameter of 200mm as shown in the figure. The interference (8) was 0.15mm. When the Young's modulus for both SS304 and 1020 steel is the same as 200GPa, and the Poisson's ratio is also the same as 0.3 for both materials, find the followings. SS 304 1020 steel Initially 100 mm Initially 200 mm Initially 300 mm (a) Pi (interfacial contact stress) (b) The maximum stresses (r and t) in the laminated steel cylinder resulting from the shrink fit.
