![]() This section deals with noncircular beams whose cross sections are not hollow. At a sufficient distance from the application of the load, however, the stresses depend only on the magnitude of the applied torque according to Saint-Venant's principle.ġ.5.2.1 Noncircular Open Beams in Torsion ![]() However, end constraint can be an important factor in the treatment of noncircular beams in torsion and is treated in Section 1.5.3.3. Since plane sections remain plane for round beams in torsion, the end constraint of such a beam does not effect its behavior. Closed beams are those with hollow sections, and other beams are called open beams. In this section, open beams are treated first and closed beams are treated second. If the stresses in such a beam are in the elastic range, the stress distribution at a cross section is as shown in Figure 1-43. This section considers the torsion of solid or concentrically hollow circular beams.ġ.5.1.1 Uniform Circular Beams in Torsionįigure 1-42 shows a uniform circular beam in pure torsion. Since the loading of the wires of helical springs is primarily torsional, they are listed under beams in torsion and treated in Section 1.5.4. Section 1.5.3 treats the membrane and sandheap analogies for beams in torsion. Noncircular beams are divided into open noncircular beams (Section 1.5.2.1) and closed or hollow ones (Section 1.5.2.2), and the effect of end restraint on noncircular beams is treated in Section 1.5.2.3. Circular beams are further divided into those with uniform cross sections (Section 1.5.1.1) and those with nonuniform cross sections (Section 1.5.1.2). ![]() Tension force on edge of membrane (lb/in)įor purposes of discussion, beams in torsion are broken into two categories: circular beams, which are treated in Section 1.5.1, and noncircular beams, which are treated in Section 1.5.2.
