Question
**Problem Statement:** 3. A cast-iron tube is used to support a compressive load, knowing that the maximum allowable change in length is 0.025%. a. Determine the maximum normal stress in the tube. b. Find the minimum wall thickness for a load of 7 KN if the outside diameter is 50 mm. **Explanation:** This problem involves calculating stress and determining dimensions for a cast-iron tube under a compressive load. The given parameters include a maximum allowable change in length and the need to find the resulting stress and necessary material thickness to safely support the specified load. - **Maximum Normal Stress:** This refers to the highest stress that the material is expected to withstand under the given compressive load. - **Minimum Wall Thickness:** This is the smallest thickness of the tube wall that ensures the structure can safely handle the specified load without exceeding the material's stress limits. **Note:** No graphs or diagrams are associated with this problem.
