For the staunch stairway find shown in Figure P5–3, determine (1) the displacements at node 2, (2) the stay reactions, and (3) the local nodal forces acting on each atom. Draw the flexible second diagram for the whole find. Remember that the direction between atoms 1 and 2 is preserved as deformation takes place; similarly for the direction between atoms 2 and 3. Furthermore, attributable to form, u2 = u3, v2 = v3, and 2 = 3. What bulk A36 steel document individuality would be needed to conduct the allowable flexible force hither than two-thirds of the resign force? (For A36 steel, the resign force is 36,000 psi.)
