(*Axialsimmetric Problems) I write the physics laws,There is shaft mounted with rim for interference with a flywheel. The three costant C1,C3,C4 I find them by imposing the boundary conditions: I don't know because Mathematica give me this error,that i've published in the picture. I try the solution exact of the three costant C1,C3,C4....... Thank you and good day!!!
