6. A rotating steel shaft is supported at the ends. It is subjected to a point load at the centre. The
maximum bending stress developed is 100 MPa. If the yield, ultimate and corrected
endurance strength of the shaft material is 300 MPa, 500 MPa and 200 MPa, respectively,
then the factor of safety for the shaft is _______
Answer: 1.9 to 2.1
