P$\mathrm{.}13\mathrm{.}2$ The relative positions of the center of gravity and the centers of pressure of the wing and

tailplane of an aircraft are shown in Fig. P$\mathrm{.}13\mathrm{.}2$; the total weight of the aircraft is $667\mathrm{.}5$ kN $.$ If the

fuselage and its contents weigh $26\mathrm{.}3k\frac{N}{m}$ and the weight of the tailplane is $8\mathrm{.}9$ kN $,$ calculate the

ultimate shear force in the fuselage at the section AA for a maneuver load factor of $3$ g including

gravity. Assume a factor of safety of $1\mathrm{.}5.$

Answer: $212\mathrm{.}2$ kN
