A compound thin cyclinder has a common diameter of 100 mm and the inner cylinder has a thickness of 2.5 mm. The radial pressure between the two cylinders is 200 kPa and the difference between the two common diameters before shrinkage was 4.305×10-3 mm. Determine (a) the thickness of the outer cylinder (b) the resultant hoop stresses in both cylinders if the compound cylinder is subjected to an internal pressure of 180 kPa. (E = 200 GPa)

A thin-walled hollow cylinder with mass m1 and radius R1 rolls without slipping on the inner wall of a larger thin-walled hollow cylinder with mass m2 and radius R2 >> R1. Both cylinders' axes are aligned and horizontal, and some magical mechanism ensures this perfect friction contact between them. Unfortunately for you, the larger cylinder rolls without slipping on a horizontal surface. Describe the motion including small oscillation frequencies near any equilibria if the systems is released from rest with...
