Question

This is the only picture that was given. I do not understand how to set up the shear stress in terms of cylindrical and spherical coordinates.

The figure below shows 3D ojects submerged in fluid. The shapes in the left column use a cylindrical coordinate system. The shapes in the right column use a spherical coordinate system.

The shaded patches represent surface elements and the arrows represent shear stresses. For each of the shapes give the component of the shear stress that is indicated.

Solid sphere dof radius R Solid cylinder of radius R a. Solid sphere of radius R e. b. Solid cylinder of radius R Solid notched cylinder C. Solid cone with half angle

Explanation / Answer

When abody is submerged in a fluid. The body is subjected to hydrostatic state of stress and there is no shear stress component in the body all the planes in the body are subjected to uniform stress and all the planes are principal planes .

Mohr's circle becomes a point.
