Air Spring Oscillators When air is contained in an enclosed space, it can act as the spring in a spring mass system. In the example shown in Fig. 6.2, a frictionless mass is backed by a volume of air. When the mass moves into the volume, the pressure increases, creating a force that...
The changes in specific internal energy and specific enthalpy of an ideal gas are given by Eqs. (3.38) and (3.42). The constant pressure and constant volume specific heats of air are found in Table 3.7 (or Table C.13) as cp = 0.240 Btu/lbm · R and cv = 0.172 Btu/lbm · R. Th...

Be familiar with the effect of air resistance on the motion of a falling object. 10. Know why velocity is a vector, whereas speed is not. 11. Remember the rules for simple manipulations of vectors. You should be able to construct the sum (or difference) of two vectors, and you should...
