At a mail sorting facility, packages slide down a ramp but are stopped part way down the ramp so that they can be scanned. while the packages are scanned, they are held in place by a horizontal force from a spring-loaded arm. calculate the minimum force that must be applied by this arm to hold a package on the ramp. the ramp is at an angle of 33.5° with the horizontal. the package has a mass of 9.25 kg. the coefficient of static friction between the ramp and the package is 0.455.

Air initially at 0.75 bar, 1000 k, and occupying a volume of 0.12 m^3 undergoes two processes. process 1-2: the air is compressed isothermally until the volume is halved. process 2-3: the air undergoes a constant pressure process until the volume is halved again. assume ideal gas behavior. a) determine the mass of the air, in kg. b) the work and the heat transfer for each of the two processes, in kj. (100 kj = 1 bar . m^3)
