Rotating Shafts and Moments

Torsional moments acting on rotating shafts

Sponsored Links

A torsional moment acting on a rotating shaft can be expressed as

M = Php 33,000 12 / (2 π w) = 63,057 Php / w         (1)

where

M = moment (in lb)

Php = horsepower (hp)

w = rotational velocity (rpm)

  • 1 hp (English horse power) = 745.7 W
