Unformatted text preview: 14185  W 16.0018.00 Name: __________________________ EM 319 Fall 2011 Quiz 11 A pressurized cylinder has a helical weld at an angle = 30 as shown in the figure. The tank has a radius r = 0.5 m, wall thickness t = 20 mm, and internal pressure p = 3 MPa. First, find the circumferential and longitudinal stresses, then transform the stresses to show the normal and shear stresses acting on a stress element that is aligned with the weld. p 3 10 6 := 30 180 := r 0.5 := t 0.02 := y p r t := x p r 2 t := y 7.5 10 7 = x 3.75 10 7 = xy := 2 := xp x y + 2 x y 2 cos 2 ( ) + xy sin 2 ( ) + := yp x y + 2 x y 2 cos 2 ( ) xy sin 2 ( ) := xyp x y ( ) 2 sin 2 ( ) xy cos 2 ( ) + := xp 6.563 10 7 = yp 4.688 10 7 = xyp 1.624 10 7 = 14202  W 18.0020.00 Name: __________________________ EM 319 Fall 2011 Quiz 11 A pressurized cylinder has a helical weld at an angle = 20 as shown in the figure.
