A stress of 73 MPa is applied in the [001] direction of a unit cell of a BCC iron single crystal. a) Draw [001] and [111] directions and (01�1) plane in the BCC unit cell. b) Calculate the resolved shear stress for the following slip system (01�1)[111].

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

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

Give heat transfer applications for the following, (i) gas turbines (propulsion) ) gas turbines (power generation). (iii) steam turbines. (iv) combined heat and power (chp). (v) automotive engines
