6-51* to 6-53* For the problem specified in the table, build upon the results of the original problem to deter-mine the minimum factor of safety for fatigue at point A, based on infinite life, using the modified Goodman criterion. If the life is not infinite, estimate the number of cycles. The force F is applied as a repeated load. The material is AISI 1018 CD steel.

3-86* Repeat Prob. 3-84 with Fx = 300 Ibf, Fy = 250 Ibf. and Fz = −100 Ibf.
3-84* The cantilevered bar in the figure is made from a ductile material and is statically loaded with Fy = 250 Ibf and Fx = Fz = 0. Analyze the stress situation in the small diameter at the shoulder at A by obtaining the following information.
- (a) Determine the precise location of the critical stress element at the cross section at A.
- (b) Sketch the critical stress clement and determine magnitudes and directions for all stresses acting on it. (Transverse shear may be neglected if you can justify this decision.)
- (c) For the critical stress clement, determine the principal stresses and the maximum shear stress.

- (b) A steel 'hot rolled structural hollow section' column of length 5.75 m, has the cross-section shown in Figure Q.5(b) and supports a load of 750 kN. During service, it is subjected to axial compression loading where one end of the column is effectively restrained in position and direction (fixed) and the other is effectively held in position but not in direction (pinned). i) Given that the steel has a design strength of 275 MN/m², determine the load factor for the structural member based upon the BS5950 design approach using Datasheet Q.5(b).
