Problem No.2
A bar of circular cross-section is subjected to alternating tensile forces varying from a minimum of 200 kN to a
maximum of 500 kN. It is to be manufactured of a material with an ultimate tensile strength of 900 MPa and an
endurance limit of 700 Mpa (the stress below which a material can tolerate repeated load cycles without failure).
Determine the diameter of bar using safety factors of 3.5 related to ultimate tensile strength and 4 related to
endurance limit and a stress concentration factor of 1.65 for fatigue load. Use Goodman straight line as basis for
design.
