IV) In the following structure consider that F is applied on the centroidal plane. Then section S is subjected to: *88 a) Shear and flexure My; b) Shear and flexure Mx; c) Shear and Torque. V) In the Saint-Venant's case of eccentric axial force, the neutral axis: a) Can be a line parallel to x-axis; b) Can be one principal axis; c) Is always a line not parallel to x-axis nor y-axis. VI) Given the following frame system, the Euler's critical load for the whole frame system is (plot the deflected structure on the right): EJ-x h/2 EJ a) P= with h; 12 *² EJ b) Pa with 2h; EJ h c) P with o "
