QUESTION -2 McDonnell Aircraft's F2H Banshee fighter first flew in 1947 and some served into the 1960s. The aircraft used 2 Westinghouse J34.WE-30 turbojets delivering 14,000 N of thrust each giving a maximum speed of 945km/h and a range of almost 2090 km . The F2H could climb at about 2250m/m in and reach a service ceiling of 14,800 m. If the airplane is operating at an altitude of 6100 m with a choked nozzle exit (Me=1,Y_(e)=1.33) and the nozzle exit area A_(e)=0.116m^2 and the exit pressure is p_(e)=62 kPa find the following; (a) gross thrust produced, (b) percentage of gross thrust caused by the pressure imbalance at the nozzle exit, (c) exit mass flow if T_(e)=537.8^circ C (d) ram drag at a flight velocity of 167.6m/s f/a=0.02 (e) net thrust, (f) thrust power produced. (g) exit velocity V_(e) (h) effective exhaust velocity V_(eff) (i) propulsive efficiency n_(p) (i) nth and n_(0) for Q_(f)=43.96MJ/kg) (k) the specific fuel consumption, cj.

A ramjet engine operates at a flight Mach number M_(0)=0.8 at 9000 m altitude where p_(0)=30.14 kPa and T_(0)=229K For an effective exhaust velocity V_(e)=760m/s and inlet cross -sectional area A_(1)=0.187m^2 calculate: (a) the air mass flow rate m_(0) (b) the fuel mass flow rate my for a fuel-to-air ratio of f/a=0.03 (c) the exhaust gas mass flow rate me. (d) the gross thrust. (e) the net thrust, (f) the thrust power, (g) the propulsive efficiency n_(p) (h) the thermal efficiency n_(th) (i) the specific fuel consumption q (i) the overall efficiency n_(0)

The lecture describes various screw head types, each suited for specific applicatio ns. Which screw head type would be the most appropria te choice for an application where the screw head needs to sit flush with the surface of the workpiece and provide a visually appealing finish? Hex Head Oval Head Pan Head Countersunk Head

The lecture emphasize the importance of washers in reducing stress concentration. If a washer is omitted in an assembly involving a bolt and nut, where is the stress concentration most likely to occur? At the interface between the bolt head and the workpiece Within the threads of the bolt In the center of the workpiece being clamped At the edges of the hole in the workpiece
