The air standard Ericsson cycle (see Figure 13.40) is made up of an isothermal compressor (T2 = T3 = TL), an isothermal prime mover (T1 = T4 = TH), and an isobaric regenerator (p1 = p2 and p3 = p4).
Show that the compressor and prime mover must have identical pressure ratios, that is, p2/p3 = p1/p4, and show that this also requires that v3/v2 = v4/v1.
A uniform bar of length l and mass m is suspended by two equal springs of equilibrium length b and force constant k , as shown in the diagram. find the normal modes of small oscillation in the plane.
