Specify where the line of action of the resultant force intersects a horizontal line along member CB, measured from end C. Express your answer to three significant figures and include the appropriate units. Enter positive value if the line of action intersects a horizontal line CB to the right from end CC and negative value if the line of action intersects a horizontal line CB to the left from end C.

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
