Neglecting the effect of bending moment on the shaft. Compute the diameter of the shaft (mm)? QUESTION 11 A gear carried by a shaft exerts a force on the shaft. The torque transmitted by the gear is equal to 377,890 N.mm. The Pitch diameter of the gear is...
Question 1: A rotating shaft with a diameter of 30 mm is made of 1018 cold-rolled steel. The stress concentration factor is 2.366, and the shear stress concentration factor is 1.75 respectively. The notch sensitivity is 0.78 and for shear it's 0.96 Estimate the factor of safety guarding against fatigue failure using modified-Goodman and Soder- berg for each of the following loading conditions: a) The shaft is subjected to a completely reversed torque of 120 N.m in phase with a...
A spherical pressure vessel, with a 600 mm inner diameter, is welded from steel plates. The welded joints are sufficiently strong and do not weaken the vessel. The plates are made from cold drawn steel 20C8 (Sut= 480 N/mm2 and Syt = 250 N/mm2). The vessel is subjected to internal pressure, which varies from zero to 10 N/mm2. The expected reliability is 50% and the factor of safety is 3. The surface finish factor is 0.8. The vessel is expected...
