 Weld Requirements:

At shear only case: 
Weld Length for shear, Lv = 8.500 in.
Shear Load per inch per weld, fv = R/Lv/2 = 20.000 / 8.500 / 2 = 1.176 kips/in/ weld 
theta = 0 deg.
cPhi  = 1.0 + 0.5 * sin(0)^1.5 = 1.000
Weld Coefficient = 0.6 * 70.000 * 1.000 * 1.000 * (2^0.5/2)*(1/16) = 1.856
Required weld size, Dv = fv/ (1/omega * coeff) = 1.176 / (0.500 * 1.856) = 1.268/16

Minimum fillet weld size : 
   At shear only load case = 0.08 in.

Dmax2 (using eqn 9-3)

Check Effective Throat:
Acute Side Effect throat  = (D1/sin(DA)) * cos(DA/2) = (0.25/ sin( 67.00)) * cos( 33.50) = 0.23 in.
Obtuse Side Effect throat = ((D2/sin(DA)-tshpl/tan(DA))*sin((180-(180-DA))/2))= ((0.44 / sin(67.00) -0.38 / tan(67.00)) * sin((180 - (180 - 67.00)) / 2)) = 0.17 in.
Total Effective Throat    = 0.23 + 0.17 = 0.40 in.
Total Effective Throat of Square Case = D1 * 2^0.5 = 0.25 * 2^0.5 = 0.35 in.
