C Dynamic Analysis and Aeroelasticity SECTION B Answer TWO questions from this section ENG2012-N The moment of inertia of a helicopter's rotor is 320kg. m². The rotor starts from rest and at t = 0, the pilot begins by advancing the throttle so that the torque exerted on the rotor by the engine (in N.m) is modelled by as a function of time (in seconds) by T = 250t. a) How long does it take the rotor to turn ten revolutions? b) What is the rotor's angular velocity (in RPM) when it has turned ten revolutions?

A) Sketch three isotherms to represent an ideal gas at three different temperatures, where T1>T2>T3. B) Using the previous problem, illustrate how attractive or repulsive force (which causes non-ideal behavior) affects the isotherm at one of the temperatures. Also indicate the corresponding compression factor Z values  * Create 2 axes that show x-axis labeled as 1/V (K) and y-axis labeled as P

The specific gravity of natural gas is A. 0.08. B. 1.00. C. 0.42. D. 0.60.

Thermodynamics : Ideal Gas Cycle You have to make a SUMMARY OF FORMULAS (entire output must fit in ONE-PAGE ONLY of your chosen paper size) about Ideal Gas Cycles (Carnot, Brayton, Diesel and Otto). Your output must include SCHEMATIC DIAGRAM (T – S or P – V DIAGRAM), SUMMARY OF FORMULAS (Heat Added, Heat Rejected, Efficiency, Net Work, Important Constants, etc.).

A student develops an engine that is believed to meet all state standards for emission control. The new engine’s rate of emission is given by E(t)=2t2where E(t) is the emissions, in billions of pollution particulates per year, at time t, in years. The emission rate of a conventional engine is given by C (t) = 9 + t2 i. At what point in time will the emission rates be the same?ii. What reduction in emissions results from using the student’s engine?

Petrol vapour and air are drawn into the cylinder, The mixture is then squeezed together, and then exploded by a spark. The explosion pushes down the piston. The exhaust gases are then expelled from the cylinder. Use the first law of thermodynamics to analyse the energy changes during the process. At each stage explain what happens to i) the pressure of the gas; ii)
