Introduction This project is intended to demonstrate students’ ability to analyse all forms of stresses and deformations in a structure. They have to carry out analysis to determine the type of stress generated in different structure members and calculate the value of these stresses. They will also be able to select the suitable material for a given member under service. In addition to applying technical knowledge in a ‘real world’ project, this would demonstrate the students’ ability to conduct group research, teamwork, technical data interpretation, software use, report writing and project management skills. Accordingly, students are required to formulate groups of 3 members. ABET STUDENT Outcome measurement: The following outcome shall be measured in the current semester across the 3 deliverables SO (5) – An ability to function effectively on a team whose members together provide leadership, create a collaborative and inclusive environment, establish goals, plan tasks, and meet objectives. The students should note that grades are not allotted for each of the below points, rather they should demonstrate all the points as per the requirements of each deliverable. Students should only follow the guidelines of each deliverable for writing reports/presentations. 5.1 Demonstrate leadership and professional behavior in teams Project Deliverable 1 5.2 Build-up and function in collaborative and inclusive environment. Project Deliverable 3 5.3 Establish goals and plan tasks to meet the objectives of the team Project Deliverable 1 5.4 Contribute to the execution of plans to meet objectives of the team. Project Deliverable 2 4 II. Learning Outcomes The project covers all learning outcomes described in the course syllabus (Refer to the syllabus for more details) and concentrate mainly in the application of the following experiences: ï‚· Develop an understanding of structures subject to all type of loading (1) ï‚· Foster effective mathematical and graphical communication skills (3) ï‚· Function on teams (5) III. Project Summary (Scenario) You are asked to study and analyze the body-building equipment shown in figure 1 (body-solid bicep/tricep machine). Your objective is to apply stress and deformation analysis to evaluate the maximum stress, deformation and the factor of safety in the main metallic arm ABCDEF (Figure 2), within the elastic domain, if the weight lifted by the machine is equal to 100 kg. Consider all rectangular hollow sections (BC & DE) as 60 × 40 × 2.9 mm and the circular hollow section (AB) having an outer diameter of 50 mm and a wall thickness of 5 mm. A 12 mm diameter pin is used at point P. To succeed your mission you should apply stress and deformation analysis to the steel arm, as mentioned in Deliverable 2. Deliverable 1: 1. Select a team leader and conduct a meeting with all the team members 2. Prepare a minutes of meeting (MOM) covering all the issues discussed in the meeting including but not limited to the following points- ï‚· Function of Team leader and team members ï‚· Prepare a Gantt chart describing all the further work that needs to be done to complete the study – a detailed Work plan. ï‚· Other project management issues including plan for periodic team meetings 5 Figure 1: body-solid bicep/tricep machine Deliverable 2: 1. Describe the problem without addressing any possible solutions – Problem definition. 2. Conduct research to complete properly any missing data or dimension and draw the sketch of the Steel Arm ABCDEF. 3. Create a simplified line diagram of the arm indicating different forces and moments. 4. Define the maximum force that the athlete can apply at both handles. 5. Conduct research and gather information to determine the materials used in the arm. Show the properties of the selected material in a table. 6. Consider the structure as fixed at portion EF and apply required stress analysis at the design critical points by determining in all members: a. the average normal stress due to axial loading if applicable, b. the average shearing stress due to transverse loading if applicable, 6 c. the maximum shearing stress due to the torsional load if applicable, d. the maximum stresses due to the bending behavior if applicable. 7. Select the maximum normal ( can be bending stress) and shear stresses. 8. Calculate the factor of safety of the machine. 9. Calculate the deflection at A. ( if the chapter is covered in class) 10. Explain how individual members have contributed as per Gantt Chart in Del 1. Figure 2: Machine Dimensions (All dimension are given in mm). Deliverable 3: 1. A Powerpoint presentation of the Del2 – each member to reflect their own contribution and how they have collaborated with team members. 7 IV.

Plagiarism ï‚· Upon suspicion and doubt of the authenticity of the work submitted, the Instructor has the right to ask the student to verify her/his work. This can be done through, but not limited to, oral examination or discussion, or any other action deemed necessary. If the student fails to prove the authenticity of the work, then the Instructor will apply the academic misconduct rules as mentioned in the AUM Student Handbook which may include awarding the work a zero grade. ï‚· You will also be held responsible if someone else copies your work – unless you can demonstrate that you have taken reasonable precautions against copying. ï‚· For a detailed description of academic misconduct please refer to the undergraduate AUM Student Handbook.
