    I haven't done this in years so I am hoping someone will refresh my memory. I need to find the maximum weight that can be handled safely on structural tubing (ANSI A500) class B - 2 x 2 x 16 ga wall. The weight will be uniformly distributed along a 48" span. The supports will be fixed at either...

    (WK^2) Weight Moment of Inertia?

    Thanks for the response, this was my line of thinking as well. What was confusing for me is that my cad software (Inventor) is giving me the Inertial properties in lbmass in^2 units. I had never really heard of or used "weight moment of inertia" before so I wanted to make sure that my I3/Izz...

    (WK^2) Weight Moment of Inertia?

    Trying to figure out the minimum HP required to accelerate a fan (blower) wheel. Nema publishes the Load Wk^2 values for motors at different RPM/HP. I have modelled the fan wheels in cad and have the inertial properties ie. mass moment of inertia in the axis of rotation (Iz). Is this the...
