4. In the figure, shaft A made of AISI 1010 hot-rolled steel, is welded to a fixed
support and is subjected to loading by equal and opposite Forces F via shaft B.
Stress concentration factors K₁ (1.7) and Kts (1.6) are induced by the 3mm fillet.
Notch sensitivities are q₁=0.9 and qts=1. The length of shaft A from the fixed
support to the connection at shaft B is 1m. The load F cycles from 0.5 to 2kN and
a static load P is 100N. For shaft A, find the factor of safety (for infinite life) using
the modified Goodman fatigue failure criterion.
