An aircraft has the following short period approximation: α/δ e= (-0.746s-208.6)/(675s^2+ 1361.6s+5452.45)

Find the natural frequency, damping ratio, and the steady-state value of AOA in response to a unit step input using the final value theorem.

Atank with constant volume contains 2.27 kg of a mixture of water phases (liquid-vapor). in the initial state the temperature and the quality are 127 °c and 0.6, respectively. the mixture is heated until the temperature of 160 oc is reached. illustrate the process in a t-v diagram. then, determine (1) the mass of the vapor in kg at the initial state, (2) the final pressure in kpa.
