The lamp frame shown in the accompanying figure has hollow, square cross sections and is made of steel, with \( E=29 \times 10^{6} \mathrm{lb} / \mathrm{in}^{2} \). Using hand calculations, determine the endpoint deflection of the cross member where the lamp is attached. Solve the frame problem \( 4.9 \) in Moaveni (p. 274) using ANSYS and solid cross-sections shown below (instead of hollow). a) Obtain and submit printed list of nodal displacements, reactions, bending moments, shearing forces; elemental stresses; and deformed geometry plot. b) Check the structural equilibrium by hand. c) Draw the variation of axial stress across the cross sections of the members at fixed support and corner points. d) Verify the bending moments and axial forces obtained from ANSYS by integrating the axial stress in the members at support and corner points.
