The Figure shows a 0.75-in-thick AISI 1020 HR
steel bar subjected to a load of (F = 1.4 kip) and
welded to a vertical support using a 7010
electrode. Estimate the shear stress for the weld.
For the AISI 1020 HR steel bar, S, = 30 kpsi, Su= 55 kpsi (from the table)
From the pattern of weld shown below, b= d = 2 in (welding table)
bd2
* = b/2
ý = d/2
A = 1.414hd
Then,
A = 1.414hd = 1.414(5/16)(2) = 0.884 in?
I= bd/2 = 2(4)/2 = 4 in
1= 0.707hl, = 0.707(5/16)(4) = 0.884 in
Primary shear:

Then, the shear stress is
