A shaft is loaded in bending and torsion such that Ma- 73.7 N-m, Ta -48.8 Nm, Mm = ? 7.5 N·m, Tm = 30.9 N. m. For the shaft, SU-630 MPa and Sy = 495 MPa, and a fully corrected endurance limit of Se -190 MPa is assumed. Let Kf - 2.13 and Kfs-1.89 Part 1 out of 2 With a design factor of 1.9, determine the minimum acceptable diameter of the shaft using the DE-Gerber criterion, the DE-elliptic criterion,...

A rotating shaft is made of 42 mm by 4 mm thick cold-drawn round steel tubing and has a 6 mm diameter hole drilled transversely through it. The shaft is subjected to a pulsating torque fluc- tuating from 20 to 160 Nm and a completely reversed bending moment of 200 Nm. The steel tubing has a minimum strength of Sut 410 MPa (60 ksi). The static stress-concentration factor for the hole is 2.4 for bending and 1.9 for torsion. The...

For a bolted assembly with eight bolts, the stiffness of cach bolt is k 1.0 MN/mm and the stiffness of the members is k26 MN/mm per bolt. The bolts are preloaded to 75 peroner of proof strength. Assume the external load is equally distrihuted to all the bolts. The bolts am M6 x1 class 5.8 with rolled threads. A fluctuating external load is applied to the cntire with P 60 kN and P - 20 kN. (a) Determine the yielding...

A shaft is to be manufactured from a steel having an ultimate tensile strength of 420 MPa, and a yield stress of 305 MPa. The shaft has a solid circular cross section of diameter 50 mm and is subjected to a sinusoidally varying torque ranging from 60 Nm to 130 Nm. It has also been established that the shaft has a fully-corrected endurance limit of 129 MPa and that a torsional fatigue stress concentration factor, kf = 2.1, exists at...
