Transcribed Image Text::-Welded tracks under torsional load: A bracket under steady load P is
welded to a beam as shown in the figure. An electrode number E60XX is utilized to weld the
plates. The thickness of each plate is 4 in. The critical point of the weld is identified as the one
furthest from the weld group centroid.

For the weld group determine the following:
(a) Location (X, 9) of the centroid G.
(b) Second polar moment of area J.
(c) Location of the critical point and the distance r to the centroid.
For the critical point determine the following:
(d) Magnitude and direction of the primary shear stress t' as a function of P.
(e) Magnitude and direction of the secondary shear stress T" as a function of P.
() Magnitude and direction of the total shear stress t as a function of P.
(g) The magnitude of the external load P for a factor of safety n = 1.75.
