A fillet-welded joint is subjected to transverse loading F as shown in the Fig. 1. Both legs of the fillets are of 10 mm size and the weld length is 30 mm. If the allowable shear stress of the weld is 94 MPa, considering the minimum throat area of the weld, the maximum allowable transverse load per weld in kN is:

In transverse fillet welded joint the size of the weld is equal to:
0.5*throat of the weld
Throat of the weld
1.414* throat of the weld

A welded connection, as shown in Fig. 2, is subjected to an eccentric force of 60 kN in the plane of the welds. Determine the size of the welds, if the permissible shear stress for the weld is 200 N/mm^2. Assume static conditions.

A plate 75 mm wide and 10 mm thick is joined with another steel plate by means of single transverse and double parallel fillet welds. The joint is subjected to a maximum tensile force of 55 kN, as shown in Fig. 3. The permissible tensile and shear stresses in the weld material are 70 and 50 N/mm^2, respectively. The length of each parallel fillet weld is:
