The stresses in plane rotating discs with two eccentric holes located in symmetry with respect to the diameter of disc are investigated by means of photoelastic reflection and stroboscopic methods. The preliminary photoelastic experiment for rotating disc without eccentric holes is conducted in order to confirm the reliability of the experimental procedure in comparison with the known theoretical solution. The epoxy disc models with two eccentric circular holes of various radii or two eccentric rectangular holes with various radius of curvatures in the both ends are prepared. The results obtained for the tangential stresses on the boundaries of holes of rotating discs are shown in diagrams.
