If a circular shaft is welded to the plate by means of circumferential fillet, then the shaft is subjected to torsional moment M. If throat of weld is t, then torsional shear stress is given by
(a) M/2πtr²
(b) M/πtr²
(c) M/4πtr²
(d) None of the listed
This was presented to me in my homework.
My doubt stems from the Welded Joints Subjected to Bending Moments concept in part Welded and Riveted Joints of Machine Design
