An idealised landing gear system of an aeroplane consists of 3 identical one-degree-of-freedom spring-mass- damper systems as shown in the figure. Construct the equation of motion of the landing gear system. If the runway surface is described as a function of time y(t) =Yocoswt. Assuming that: Y₁ = 0.2m and w = 158rad/s, determine the values of spring stiffness, k, and damping coefficient, c, that limit the amplitude of vibration of the aeroplane to 0.085m when it is landing in the two cases: a. The aeroplane is empty with the total mass of 9500kg. b. The aeroplane is fully loaded with the total mass of 40,000kg x(0)

Q3: Consider evaluation of different temperatures of solar photovoltaic/thermal system (PVT) as shown in Figure 1(a). The following set of differential equations represent energy balance equations to be solve using matrices and eigenvalues dTglass = -0.75Tglass + 0.75TPVT (1) dt - 1.18Tglass – 22TpyT + 237wax (2) dt dTwax 12Tglass + 18TpyT – 19 Twax (3) dt Where, Tptass, TPVT, and Twax, are temperatures illustrated in Figure 1(b). At time t-0 the initial conditions are Tglass = 35 , Tpyr = 33, and Twax = 31 °C.
