Problem 4 Press-Fit (3-116) Matlab Code is for (3-117)
The table gives data concerning the shrink fit of two cylinders of differing materials and
dimensional specification in inches. Elastic constants for different materials may be found in
Table A-5. Identify the radial interference &, then find the interference pressure p, and the
tangential normal stress on both sides of the fit surface. If dimensional tolerances are given at
fit surfaces, repeat the problem for the highest and lowest stress levels.
