A shaft is loaded in bending and torsion such that Ma = 600 lbf · in, Ta = 400 lbf · in, Mm = 500 lbf · in, and Tm = 300 lbf · in. For the shaft, Su = 100 kpsi and Sy = 80 kpsi, and a fully corrected endurance limit of Se = 30 kpsi is assumed. Let Kf = 2.2 and Kf s = 1.8. With a design factor of 2.0 determine the minimum acceptable diameter of the shaft using the
(a) DE-Gerber criterion.
(b) DE-elliptic criterion.
(c) DE-Soderberg criterion.
(d) DE-Goodman criterion.
Discuss and compare the results.
Mechanics of Materials: Torsion » Mechanics of Slender Structures – Torsional Deformation. Torque is a moment that twists a structure. Unlike axial loads which produce a uniform, or average, stress over the cross section of the object, a torque creates a distribution of stress over the cross section. To keep things simple, we're going to focus on structures with a circular cross…This preview shows page 1 – 2 out of 2 pages.

Shaft deflection is small so that locations and directions of loads are constant with respect to the shaft.A shaft is loaded in bending and torsion such that 푀푎 = 70 푁 · 푚, 푇푎 = 45 푁 · 푚, 푀푚 = 55 푁 · 푚, and 푇푚 = 35 푁 · 푚. For the shaft, 푆푢 The shaft is to be made of SAE 2340 steel, heat-treated to obtain minimum strengths in the shoulder area of 175 kpsi ultimate tensile strength and 160…Shaft Design Problem for Combined Bending and Torsion. Refer the picture above, apart from the self weight (1000N) of the pulley a torque (1000 N-mm) due Most of the time you will come across a shaft design problem with the combination of bending and torsional loading. Accurate use of the four…
[Solved] A shaft is loaded in bending and torsion such… | SolutionInn – Shafts are generally subjected to bending moment, torsion and axial force or a combination of these three. So the shafts are designed depending upon the combination of loads it is subjected to. Maximum principal stress is given by, is called equivalent bending moment, Me, such that.If the shaft is loaded only in torsion, then one of the principal stresses will be in tension and the other in compression. These stresses are oriented at a In the case of thin hollow shafts, a twisting buckling mode can result from excessive torsional load, with wrinkles forming at 45° to the shaft axis.Keyways such as parallel and rectangular keys are used on shafts to connect and retain sub components such as gear drives, pulleys etc to transmit power. Shaft and hub keyways are often cut on key seating machines but can also be made using broaching, milling, shaping, slotting EDM.
