Coursework Overview
As a mechanical engineerer in a naval architecture company, you are asked to design a marine crane for a container ship and write a design report to the project manager. The heaviest container for the crane to lift is 80 tons. The dimension requirement of the crane structure is given in the figure below. The whole structure is composed of four steel members connected to each other by pins. The density, Young's modulus and yielding stress of steel are respectively p = 7860 kg/m3, E. 200 GPa, 5y. 250 MPa.

You need to determine the size and cross section of each member to avoid buckling failure and yielding. Moreover, you need to reduce the product cost by using as few materials as possible, i.e. lightest crane. You also need to maintain the rigiditiy of the structure, i.e. smallest displacement of the holding point B.
Coursework Tasks to be Completed by Students
• Propose rough concept designs of marine crane
• Determine the dimension of each design by considering buckling and yielding failures
• Compare proposed designs by weight and rigidity
• Choose the best design
• Write a design report (s 3000 words)
The template of the report is given below:
- Cover page
- Table of contents
- List of figures
- Section 1. Project introduction
- Section 2. Proposed designs
- Section 3. Buckling and yielding considerations
- Section 4. Design comparison and conclusion
- Appendix (if applicable)
