Output
PROC004 JIB HEEL TUBE, Rev Date, 181295
Ab	= 2(WbTf+Do*Tw)	= 156.6
Iy	= 2(TwDoWb^2/4+TfWb^3/12)	= 5.118E4
Pl	= Px/2+My/Wb	= 43.67
fd	= Px/Ab+FNsgn(Px,My)My(Do/2)/Iy	= 0.484
fs	= (Pl-fdTwDo)2/(PI((Do+Di)/2)*(Do-Di)/2)	= 0.6566
UF	= fd/(Kd(Nk)*Fy(Nm))	= 0.2064
UF	= fs/(Ks(Nk)*Fy(Nm))	= 0.4828
w	= fdTwDo/(Kt(Nk)*(Do-Di))	= 1.625
