Technician A says that deceleration during braking produces an effect called inertia shift that moves weight from the rear axles and transfers it forward. Technician B says that deceleration during braking
produces an effect called fulcrum shift that moves weight from the rear axles and transfers it forward.
Who is correct?

Air inially occupying a volume of 1 m2 at 100 kpa, 27 c undergoes three internally reversible processes in series. process 1-2 compression to 500 kpa during which pv constant process 2-3 adiabatic expanslon to 100 kpa process 3-1: constant-pressure expansion to 100 kpa (a) calculate the change of entropy for each of the three processes. (b) calculate the heat and work involved in each process. (c) is this cycle a power cycle or refrigeration cycle?
