Consider the propeller-driven general aviation aircraft in steady level longitudinal flight with a constant lift coefficient of 0.95.
a) what is the range of the aircraft in flight at an altitude of 2,000 ft? what are the initial airspeed, elevator deflection, and throttle setting with a full fuel tank? what are the terminal airspeed, elevator deflection, and throttle setting when the fuel tank is empty?
for a propeller-driven general aviation aircraft, wing surface area is 175ft^2. weight of the aircraft with a full tank is 2,900lbs. weight of the aircraft with an empty tank is 2,530lbs. the power specific fuel consumption rate is 0.45lb fuel/hr/hp. the air density at an altitude of 2000ft is 2.2409x10^-3 slug/ft^3. k=0.054. cd=0.026.

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
