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 8, 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.

**Problem 4 Press-Fit (3-116) Matlab Code is for (3-117)** The table provides data related to the shrink fit of two cylinders made of different materials, with dimensions specified in inches. Elastic constants for various materials can be found in Table A-5. The tasks include identifying the radial interference \( \delta \), calculating the interference pressure \( p \), and determining the tangential normal stress on both sides of the fit surface. If dimensional tolerances exist at fit surfaces, the problem should be solved for the maximum and minimum stress levels. **Table Description:** - **Columns:** - **Problem Number:** Identifies the scenario. - **Inner Cylinder:** - **Material:** The material of the inner cylinder. - \( d_i \): Inner diameter. - \( d_0 \): Outer diameter. - **Outer Cylinder:** - **Material:** The material of the outer cylinder. - \( D_i \): Inner diameter. - \( D_0 \): Outer diameter. - **Rows:** - **3-116:** - Inner Cylinder: Steel, \( d_i = 0 \), \( d_0 = 2.002 \) - Outer Cylinder: Steel, \( D_i = 2.000 \), \( D_0 = 3.00 \) - **3-117:** - Inner Cylinder: Steel, \( d_i = 0 \), \( d_0 = 2.002 \) - Outer Cylinder: Cast iron, \( D_i = 2.000 \), \( D_0 = 3.00 \) This table serves as input data for calculating stress levels and interference parameters in press-fit applications.
