Shafts Subjected to Twisting Moment Only
When the shaft is subjected to a twisting moment (or torque)
only, then the diameter of the shaft may be obtained by using the
torsion equation.

1. An ideal Otto cycle has a compression ratio of 8. At the beginning of the compression process,
air is at 95 kPa and 27C, and 750 kJ/kg of heat is transferred to air during the constant-volume
