Engineering mechanics

This work treats structural and continuum mechanics in a unified and consistent manner.All theoretical developments are presented both in the text and by means of an extensive set of figures. Text and figures complement each other, and this twofold presentation is also used in the examples. Volume 2 covers stresses and strains in simple elements subjected to extension, bending, shear and torsion. For elementary structures like trusses, beams and frames, displacements due to simple loads are obtained using both classical mathematical descriptions with differential equations and engineering methods like Williot diagrams for (simple) trusses and "forget-me-nots" and moment-area formulae for bending.
