The vibration is the vertical direction of an airplane and its wings can be modeled as a three-degree-of-freedom system with one mass corresponding to the right wing, one mass for the left wing, and one mass for the fuselage. The stiffness connecting the three masses corresponds to that of the wing and is a function of the modulus E of the wing.3 -3 0x0 2 RER 0 0 11 -3311X1110a) The model is given in Figure P4. Calculate the natural frequencies and mode shapes. Plot the mode shapes and interpret them according to the airplane's deflection.b) Consider the airplane of Figure P4 with modal damping of with 0.1 in each mode. Suppose that the airplane hits a gust of wind, which applies an impulse of 3?(t) at the end of the left wing and ?(t) at the end of the right wing. Calculate the resulting vibration of the cabin [??2(??)].c) Consider again the airplane of Figure P4 with 10% modal damping in each mode. Suppose that this is a propeller-driven airplane with an internal combustion engine mounted in the nose. At a cruising speed the engine mounts transmit an applied force to the cabin mass (4m at ??2) which is harmonic of the form 50??????10??. Calculate the effect of this harmonic disturbance at the nose and on the wind tips after subtracting out the translational or rigid motion.

In the homogeneous decomposition of nitrous oxide N20 to form nitrogen and oxygen, it is found that at constant temperature the time needed for half the reaction to be completed (T1/2) is inversely proportional to the initial pressure (po) of N2O. On varying the temperature the following results were obtained. Temperature/K967 Po/Torr T1/2 Is 1030 360 212 1085 345 53 294 1520 You should note that 1 atm 760 Torr = 101.325 kPa, and you may assume that N2O behaves as an ideal gas. Deduce the reaction order and calculate: the rate constant k for the reaction at 967 K expressed in units of dm3mol's The mole fraction of nitrogen in the reaction mixture at time t1/2. (ii)

You are tasked with the design of a double- reduction gear train to transmit power and motion from a motor-powered input shaft (a) to an output shaft (C). The input shaft and its bearings are not your concern, but the gear on the input shaft and the gears, bearings, and shaft design for the remaining shafts are your responsibility. Your specific design parameters are listed on the back of this page. 0 Press InPwr InSpd OutSpd Ang Length hp rpm rpm deg inch InLife rev's 20 1176 324 25 11 2.50E+08
