A circular column is subject to a fluctuating bending stress, which varies between 10,000 psi and 30,000 psi. The material used for this column is 3140 OQT1300 steel. Stress concentration factor is 1.30 and the actual endurance limit ( Sn' ) for this material is 42 ksi. Determine the design factor N, using Goodman Criteria.

It is desired to determine the diameter of a cold drawn steel bar to withstand a tensile preload of 36 kN and fluctuating tensile load varying (0- 72) KN. The bar have geometrical stress concentration factor K. = 2.02 corresponding to a fillet radius of 3.5 mm. Find diameter for infinite life Use: safety factor = 3, S. = 510 Mpa, S .. = 650 Mpa and uncorrected endurance limit = 364 Mpa
The beam is designed to carry a fluctuating stress from a load of 1,200-lb. The beam is made of Cold-Drawn AISI 1040 steel (wrought steel). Using the Goodman Method for Fatigue of Ductile materials, determine the design factor, N. 10 in 1200 lb 10 in 2-in dia
A gear made of aluminum (modulus of elasticity = 69,000 MPa) is press fitted onto an aluminum shaft. The gear has a diameter of 55 mm at the base of its teeth. The nominal internal diameter of the gear = 30 mm and the interference = 0.10 mm. Compute: (a) the radial pressure between the shaft and the gear, and (b) the maximum effective stress in the gear at its inside diameter.
