Determine the effort distributions in the structure elements in Figure $01,$ plates $-$ shear flow and reinforcers $-$ standard force diagram, exclusively in bar $"$e$",$ assuming that the shear resistance is exclusively the plates and that the resistance to Normal longitudinal stresses apply exclusively to the reinforcing bars. Finally, carry out a simplified analysis of the panels stability. Data $-$ thickness of all sheets is $0\mathrm{.}1$ cm and the material of the reinforced panel is characterized by the longitudinal modulus of elasticity E$=3,000\mathrm{.}00$ kN$/$em$\text{'}.$
