Exercise 1 Course of Spacecraft Structures \Vritt e!l test. September 3rd . 2018 Determine the internal shea.r stresses for the beam section reported in the figure . Five of the stringers have equivalent area (including pane! contributi on) equa! to A , while one string er (see figure) has equiY alent area 2A. The panels ha,·e thickness t. The internal shea.r force is denoted with T . r Data R1 = 200 mm; R2 = 400 mm ; A = 250 mm2 ; t = 0.6 mm; T = 50 kN ; Exercise 2 A beain is charact erized by length I and bending stiffness EJ. It is cla.mped a.t both the ends and is subjecc ed co a linearly varying vertica.l force per unit length, a.s reported in the figure. Determine the displacement at a distance of //4 from the constraint by solving the problem by means of: • a force-based approach (exact solution) • a displacement-based approach (exact solution) q ~ --=-::q__JJJJ l. EJ Que~tiou l Inustrate how che serui-rnonocuque scheme cau be applied for evaluat ing the section properties of a tl11n-walled bea.111. Discuss the rele,·am equatiou s and darify the hypothesis / assumpt ions of the models ernployed.
