Question #239558

A 65mm diameter solid shaft is to be welded to a flat plate by a fillet weld

around the circumference of the shaft. Determine the size of weld if the

torque on the shaft is 3KN-m. The allowable shear stress in the weld is 70

N/mm2

around the circumference of the shaft. Determine the size of weld if the

N/mm2

Expert's answer

If, h= Size of fillet weld

t= throat thickness

T= Torque applied

The maximum shear stress developed in the weld material is given by,

Given as

Solving for t, we get

Size of weld(h)=
