Given loads:
For the specified loading case:
•
Calculate the force per inch of weld for each of the stress components: the
vertical shear, the bending, and the torsion.
Determine the combined resultant force per inch of weld.
For the specified weld size, calculate the maximum combined shear stress in the
weld throat. Answer: Tmax=25.6 psi
T = 15,000 in-lbs

• Using the maximum allowable shear stress for A36 steel and a weld electrode
of E70 (see Table in your textbook), calculate a new weld size for the same load
conditions.
The weldment shown in Figure 2 is subjected to an alternating force F. The hot-rolled steel
bar is 10 mm thick and is of AISI 1010 steel. The vertical support is likewise of 1010 steel.
The electrode is 6010.
(a) Estimate the fatigue load F the bar will carry if three 6-mm fillet welds are used.
