Design of Lifting Lug Weld

Design By:

P = 5.5 kip

θ = 70 degrees Angle Between Y-Axis and P

S.F. = 3 Safety Factor

Px = 5.17 kip

Py = 1.88 kip

b = 0.5 in

d = 4.5 in

Aw = 10 in

c = 2.25 in Distance from Px to Plate

Mu = 11.63 kip*in

Sw = 9.00 in2

fb = 1.29 kip/in

ft = 0.19 kip/in

fv = 0.52 kip/in

fr = 1.568 kip/in

D= 2.53 Weld Size in Sixteenths of an Inch

For E70 Electrodes

NOTE: Weld size is based on weld load only. Base material should

also be checked!
