A thick-walled cylinder has an outer and inner diameter of 200 and 50 mm, respectively. The  cylinder is designed to store fluid at 80 MPa: (a) Determine the external pressure necessary to bring the hoop stress at the outer wall of the  cylinder to zero.  (b) Draw the variations of the hoop and radial stress across the thickness of the wall. Indicate  the stress values at both inner and

i need the answer quickly

A plane stress state is given by the principal stresses σx =25 MPa and σy= -11 MPa. Determine σx' in the case that the system is inclined by 30 degrees (counter-clockwise). Give your answer in MPa to the nearest whole number.

The inner diameter of the AB compressed air tank is 160, the wall thickness is 1.Since the manometer pressure in the tank is 1,6 ,at point a at the top of the tank maximum normal stress and determine the maximum plane shear stress.(c=16  ,   d=38,   e =32,   g=160,       h=1,  k =1.6 ,   F=160)

-8 in.- -8 in.- (a) (b) Which of the following best explains why cylinder (b) has a higher longitudinal stress in its walls compared to cylinder (a)? Assume the gauge pressure of the fluid inside the cylinder is non-zero. O Cylinder (b) is supported at two locations Cylinder (a) is not free to deform in its longitudinal direction The vertical (longitudinal) pressure in cylinder (a) is transferred directly to the [bottom] support, bypassing the cylinder walls None of the above the longitudinal stress for both cylinders is the same

Mohr's Circle The major and minor principal stresses acting at a point are 80 psi compression and 20 psi tension. (a) Draw the Mohr's circle for this stress combination. (b) What is the maximum shear stress acting at the point, and what value of normal stress acts on the plane? (c) Determine the value of the shear and normal stress acting on a plane that is 30° from the major principal plane. kindly answer the following with a complete solution so that i can understand how to solve it. thank you

Investigate which problem can be solved by the two-dimensional stress distribution o11 = Ax,x2; 012 = B + Cx3; 022 = 0, where A, B and C are constants, in the absence of body forces. Assume a rectangular solid defined by 0 < xsl and -h < x2 < h with l » h. Explicitly determine the required constants A, B and C to solve the problem.
