Amaterial is subjected to a horizontal tensile stress of 90 mpa, a vertical tensile stress of 120 mpa and a shear stress of 75 mpa. find: . the principal stresses .the maximum shear stress the shear stress, acting alone that would produce the same the single tensile stress, acting alone that would produce the same principal stresses maximum shear stress

Inspection for bearing condition will include: (clo4) a)-color b)-smell c)-size d)-none of the above

Wiy doeres rere okhn a pump whon working betwon the same pressure range?

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?
