Arotary actuator has the following physical data: outer radius of rotor rr = 0.80 in outer radius of vane rv = 1.7 in width of vane l = 0. 5 in if the torque load is t = 900 in∙lb, what pressure p must be developed to overcome the load?

Burgers vector is generally parallel to the dislocation line. a)-true b)-false

Air is compressed isentropically from an initial state of 300 k and 101 kpa to a final temperature of 1000 k. determine the final pressure using the following approaches: (a) approximate analysis (using properties at the average temperature) (b) exact analysis

Asteam is contained in a rigid tank with a volume of 1 m3. initially, the pressure and temperature are 7 bar and 500 oc, respectively. the temperature drops due to cooling process. determine: (1) the temperature at which condensation begins in °c, (2) the fraction of the total mass that has condensed when the pressure decreased to 0.5 bar. (3) the volume in m3 occupied by saturated liquid at the final state?
