The 18 mm diameter shaft is made of A-36 steel, G=75GPa with an allowable shear stress of 60 MPa. a. Knowing now what section has the maximum absolute value of torque, and knowing the max allowable shear stress, compute the maximum value for T. b. With this value of T, calculate the angle

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false

Air is flows through an adiabatic nozzle with an inlet pressure of 400 psia at a temperature of 300°f and a velocity of 20 ft/s. the outlet pressure is 40 psia and the velocity is 800 ftl/s. determine the outlet temperature of the air using: a) property tables b) specific heat (using the specific heat value for air at 300°f)
