Learning goal: to understand the parallel-axis theorem and its applications to solve many problems about rotational motion, it is important to know the moment of inertia of each object involved. calculating the moments of inertia of various objects, even highly symmetrical ones, may be a lengthy and tedious process. while it is important to be able to calculate moments of inertia from the definition (i

The air in an automobile tire with a volume of 2.60 ft3 is at 70°f and 21 psig. determine the amount of air that must be added to raise the pressure to the recommended value of 30 psig. assume the atmospheric pressure to be 14.6 psia and the temperature and the volume to remain constant. the gas constant of air is ru = 53.34ft⋅lbflbm⋅r(1 psia144 lbf/ft2) = 0.3704 psia⋅ft3lbm⋅r the amount of air that must be added to raise the pressure is lbm
