Consider A Low Wing Monoplane Eg Cessna 350 With A Mtow Of 15 Kn And With Two Wings In A Rectangular Plan Form Fig 1 (64.88 KiB) Viewed 71 times

Consider a low wing monoplane (eg., Cessna 350) with a MTOW of 15 kN and with two wings in a rectangular plan form. Fig. 1 depicts the basic dimensions of one wing which is placed in a three dimensional Cartesian coordinate system. Assume that: (a) the aircraft is in 1-g steady level flight, and the tail produces a downward load equal to 10% of the MTOW; (b) each wing provides 12 of the total lift force of the aircraft (no body lift); (b) the lift on the wing has a sinusoidal distribution as shown in Fig 1; and (c) the centroid of the wing is 350 mm aft the leading edge. For the 1-g level flight determine: (a) the value of coefficient A in the sinusoidal lift distribution; (b) the distribution of the shear force Sy(z), the bending moment Mz(z), and the torque T(z) along the wing created by the lift.
