shaft midway

Example 6.14. A pulley is keyed to a shaft midway between two bearings. The shaft is made of
cold drawn steel for which the ultimate strength is 550 MPa and the yield strength is 400 MPa. The
bending moment at the pulley varies from – 150 N-m to + 400 N-m as the torque on the shaft varies
from – 50 N-m to + 150 N-m. Obtain the diameter of the shaft for an indefinite life. The stress
concentration factors for the keyway at the pulley in bending and in torsion are 1.6 and 1.3 respectively.
Take the following values:
Factor of safety = 1.5
Load correction factors = 1.0 in bending, and 0.6 in torsion
Size effect factor = 0.85
Surface effect factor = 0.88
