Question

1. Sketch stress distribution in the cross-sections (defined by the dashed-lines) for the following loading cases. If there are both normal and shear stresses, sketch them separately. Also indicate the subscripts for each stress component you sketch, according to the given coordinate system. a) Uni-axial (2pts) b) Torsion (2pts) (for this case use cylindrical coordinate to determine the subscripts of the shear stress, axial direction x-axis, radial direction r, and circumferential direction e.) C) Transverse loading 1 (3pts) d) Transverse loading 2 (3points) Coordinates for c) and d)

Answer 1

Ans: ay uni-anial The load is uni-axial, so oniy tensile stress will be Produced Staess-distaribution C0055 Section b) Toursion: Due to tousion only shear stress will be generated Storess - distaibution

c) Toransverse loading.': Due to transverse load shead and bending Storess will be produced. Bending Storess shear stress - tensile compressive Taransverse loading 2: KO Bending stress tensile shead storess Shead storess comporessive → only direction will be changed.
