A circular plate 100 mm diameter is welded to another plate by means of 6 mm size fillet weld. If the permissible shear stress in the weld is 100 n/mm2, then the greatest twisting moment that can be resisted by the weld is

The greatest twisting moment that can be resisted by the weld is
Given:
Diameter of the plate = d = 100 mm
Size of another plate = 6 mm
Shear Stress = 100 = 10.2
To find:
Greatest twisting moment = ?
Formula used:
Where,
P = Permissible stress
Solution:
From the question, fillet weld is used to join the two plates. Thus, the two plates are perpendicular to each other.
The allowable force is less than 70% when the welds were placed perpendicular to the applied load.
Strength of weld:
Length of weld:
Twisting moment:
