T= 550 kip-ft
Plane of weld
Figure P6-89
Transcribed Image Text:P= 28 kip -Rigid plate T= 550 kip-ft Plane of weld Figure P6-89
6-89 A thin-walled cylindrical pressure vessel with an inside di-
ameter of 4 ft is fabricated by butt-welding 0.6-in.-thick plate
with a spiral seam as shown in Fig. P6-89. The pressure in the
tank is 360 psi. Additional loads are applied to the cylinder
through a rigid end plate as shown in Fig. P6-89. Determine
a. The normal and shearing stresses on the plane of the weld
at a point on the outside surface of the tank.
b. The principal stresses and the maximum shearing stress at
a point on the inside surface of the tank.
