4. The masses and coordinates of four particles are as follows: 50g, x = 2.0 cm, y = 2.0 cm; 25g, x = 0, y = 4.0 cm; 25 g, x = −3.0 cm, y = −3.0 cm; 30g, x = −2.0 cm, y = 4.0 cm. What are the rotational inertias of this collection about the a) x, b) y, and c) z axes? d) Suppose that we symbolize the answers to a) and b) as A and B, respectively. Then what is the answer to c) in terms of A and B?

As part of an industrial process, air as an ideal gas at 10 bar, 400k expands at steady state through a valve to a pressure of 4 bar. the mass flow rate of air is 0.5 kg/s. the air then passes through a heat exchanger where it is cooled to a temperature of 295k with negligible change in pressure. the valve can be modeled as a throttling process, and kinetic and potential energy effects can be neglected. (a) for a control volume enclosing the valve and heat exchanger and enough of the local surroundings that the heat transfer occurs at the ambient temperature of 295 k, determine the rate of entropy production, in kw/k. (b) if the expansion valve were replaced by an adiabatic turbine operating isentropically, what would be the entropy production? compare the results of parts (a) and (b) and discuss.

In a game of pool, ball a is moving with a velocity v0 of magnitude v0 = 15 ft/s when it strikes balls b and c, which are at rest and aligned as shown. knowing that after the collision the three balls move in the directions indicated and assuming frictionless surfaces and perfectly elastic impact (that is, conservation of energy), determine the magnitudes of the velocities va, vb, and vc.
