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...

Question 2: [20 Points) The Figure below shows a portion of a pump that is gear driven at uniform load and speed. The shaft is supported by bearings mounted in the pump housing. The shaft is made of steel, its yield strength is 800 MPa and its ultimate tensile strength is 1000 MPa. The surface of the shaft is machined. Due to the fillet at A, the fatigue bending stress concentration factor is 2.0, the fatigue torsion stress concentration factor...

Please answer A and B.
The rotating solid stedl shaft is simply supported by bearings at points B and C and is driven by a 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...

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...

ME 117 Final The disk sander shown in the figure has a steel shaft with a yield strength of 600 Mpa and an ultimate strength of 700 Mpa. The most severe loading occurs when an object is held near the periphery of the disk (100 mm radius) with sufficient force to develop a friction torque of 16 N·m. Assume a friction coefficient of 0.6 between the object and the disk. What is the safety factor with respect to eventual fatigue...

A couple is applied to the ends of the rotating steel shaft as shown below with a force F= 350 lb, in the form of a repeated loading. The shaft is commercially grounded. The following properties are specified for the material Sut = 110ksi and Sy = 80ksi. The reliability specified is 95%. Find the factor of safety for the 8in shaft using the Modified Goodman Design Theory for infinite life. Ignore the stress concentration at the fillet.
