RE: Metric Steel Shapes

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Why change mass to force (kg to N) to convert back to 
mass??????

Unless I missed something all these years, lb/ft of the beam is 
mass per foot length...not pound force per foot......

(I am really starting to miss the metric system.....sob...sob...)
