| Abstract: | In some extensively used textbooks on plasticity tha problem of three rods under tension forming a truss is discussed. In its elastic-plastic analysis is often seen some form of an illustration showing the relations between the load and the displacement occuring in the joint where the rods are bound together. The paper seeks to explain some impropriety of the illustration. An amendment to the figure is proposed. |
