The rotating solid steel shaft is simply supported by bearings at points B and C and is driven by gear (not shown) which meshes with the spur gear at D
The rotating solid steel shaft is simply supported by bearings at points B and C and is driven by gear (not shown) which meshes with the spur gear at D, which has a 150-mm pitch diameter. The force F from the drive gear acts at a pressure angle of 20". The shaft transmits a torque to point A of TA = 340 N.m. The shaft is machined from steel with Sy= 420 MPa and Sut = 560 MPa. The fatigue...

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...

Problems 1. (Subtotal: 21 points) A steady torque of 1500 Ibf in is transmitted by a machined shaft made of steel with an ultimate tensile strength of 100 kpsi. The transverse cross section at the location of a shoulder against which a gear sits is subjected to a bending moment which is a sinusoidal function of time with a maximum of 800 lbf-in. Furthermore, this cross section is the location for the maximum von Mises stress. The smaller diameter at...
