Suppose the viscous stress tensor at point p in a fluid is given by sigma = (sigma_xx 4 2 4 0 3 2 3 0) where sigma_xx is unknown. determine sigma_xx so that there is a plane with unit normal n on which the traction vector t = n middot sigma vanishes. determine n.

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

When at a point two solid phase changes to one solid phase on cooling then it is known as a) eutectoid point b) eutectic point c) peritectic point d) peritectoid point

Two technicians are discussing the intake air temperature (iat) sensor. technician a says that the computer uses the iat sensor as a backup to the engine coolant temperature (ect) sensor. technician b says that the powertrain control module (pcm) will subtract the calculated amount of fuel if the air measures hot. who is correct
