    rotating shaft considering self load and overcome the friction

    I was trying to use hp = T*n/63 Where T is in Kips, represented T = I*angular accel In the formula P= 2*3.142*T*N/60 What is the unit for T

    rotating shaft considering self load and overcome the friction

    I appreciate your time desert fox. Many thanks. I think this much of info can get me started. I was missing angular acceleration. And also I believe I can get the friction factor from the manufacturer of bearing and I can use that too in this formula.

    rotating shaft considering self load and overcome the friction

    Consider shaft just needs to be rotate gradually increasing to 60 RPM. Consider Ball or roller type bearing of SST. Also if possible please let me know which formula do I use to calculate starting torque and required power to keep this shaft rotating. Thanks for responding.

    rotating shaft considering self load and overcome the friction

    I am trying to rotate 60" long shaft of dia 4" made of SST 630 need to rotate at 60 rpm. If the shaft is resting on a bearing at both the ends, which formula do I use to calculate the power required to rotate this shaft considering self load of shaft and overcome the friction of bearing.
