Louie David Y. Almazar December 16, 2020 BS – Mechanical Engineering BME 212L 3:30 – 4:30 PM BME FINAL EXAMINATION I. Pre-Credit a. Brief Description I am a Mechanical Engineering student that transferred from the Ateneo de Davao University. I chose this course because I eager to learn about how things work, and I wanted to get knowledge about different engineering courses that is why I chose the ‘Mother of Engineering Courses’. I attended mechanical engineering related seminars and experienced programming robots, such as Arduino robots, which were fun and helped expand my imagination in this field. Also, I find hands-on activity fun and interesting which is also why I chose this course. However, I lack the skills needed in Welding, Drilling, and other workshop activities yet, I am willing to learn and progress as an aspiring engineer and gain more knowledge and experience about this profession and its activities. b. Introduction to the Topic Mechanical Engineering is considered as the Mother of engineering courses because it is considered as broad and serves as basis of other engineering courses. In this course, aspiring engineers are to learn and master different skills in order to become a true engineer. To be equipped with these skills, especially in workshop operations, will allow us to design and create interesting inventions or innovations. This subject provides the information and teaches us the basic concepts of the operations done in a workshop. It is in us to master and put into action the lessons discussed. II. Present the Learning Outcome of this Output The Final Examination is to design and construct a Grill Box. In this activity, we will showcase the skills and lessons we learned from this subject. Also, here, we are going to apply the importance of safety and, follow and wear the proper protective equipment for this activity. There will be activities such as welding, cutting metal, proper positioning, and other guidelines that will be performed. The output for this examination will provide an approval of the things learned from this subject. III. Present the Discussion Proper (follow the flow below) a.

Detailed Steps and Workshop Operations and Process in making the Grill Box Grill Box Body: Step 1: - Prepare all materials and equipment needed as stated above. Step 2: - Place the necessary materials in a safe location to avoid hazards. Step 3: - Get the Plain Sheet Metal and cut a 31 x 17in. size using a sheet metal Scissor. Step 4: - Cut 3in. and Fold 3in. on the sides of the Sheet Metal (Follow the picture below) Step 5: - Weld the corners to maintain the structure of the body. Grill Box Cooking Grid: Step 1: - Measure, with a steel tape, and cut 72in. from the 9mm Steel Rod for the frame with the use of a Hacksaw. Step 2: - Divide the 74in. rod by four parts and mark each part by: 11 – 26 – 11 – 26in, accordingly. Step 3: - Fold the marks of the steel rod and make a rectangular shape. Step 4: - Weld the two points together to complete the Cooking Grid frame. Step 5: - Measure and cut 2 pieces, 11in. long from the remaining 9mm Steel Rod using a Steel tape and Hacksaw. Step 6: - Attach the two pieces to the frame of the cooking grid, with a gap of 8.5in. Then, weld the intersections of the 11in. steel rods to the frame. See picture below as guide: Step 7: - Measure and cut 2 pieces, 11in. long from the remaining 9mm Steel Rod using a Steel tape and Hacksaw. Step 8: - Attach the 2 pieces to the sides (26in. side), with 8 in. gaps from each other and the ends. Then, weld the pieces and the frame altogether. Step 9: - Measure and cut 10 pieces, 26 in. long from the remaining 9mm Steel Rod using a Steel tape and Hacksaw. Step 10: - Place the steel rods horizontally on the frame with 1 in. gap from each other. Then, weld the steel rods to the Frame. e. Documentation and Explanation on the actual making of the Physical Output of your Grill Box. Compare Output to your Plan There was a lot of things to do before doing the actual making of the grill box. I went to a nearby junk shop and bought 5 kg. of Plain Sheet Metal. Then I went to a nearby hardware store and bought the other materials needed in making the grill box such as welding rod, 9mm steel rods, and a 10mm steel rod. Before doing the activity, I made sure to wear the proper protective equipment and prepare all the materials and equipment needed in making the grill box. The first thing I did was make the body of the grill box. I measured and cut the plain sheet and folded it in order to have the form of the body. However, I forgot to take a picture of the body. Then, I decided to build a stand for my grill box in order for us to experience no back problems when using the final output. This was not included in my original plan. I measured and cut the 10mm Steel Rod by 4 pieces of in. Then, 2 pieces each measuring 26in. 11in. and 14in. And lastly, 1 25 in. I then formed the frame and weld them altogether. I realized that I needed gloves, so I went to the hardware and bought some gloves to ensure my safety. Before welding, I placed the materials in a safer place, and I set the welding machine and adjusted the voltage before doing the activity Next, I proceeded to do the Grill Box Cooking Grid. I measured and cut a 72 in. long from the 9mm Steel Rod and folded it into four parts, 11 – 25 – 11 – 25 accordingly. Then I welded the end together to make the frame. I then cut 10 pieces of 25in. 9mm Steel Rods. After, I welded the 25 in. steel rods to the frame with a 1 inch gap from each other. I then attached the body of the grill box to the stand and welded them together. I decided to put a layer of metal at the base of the body just to make sure that the base is more durable and won’t get destroyed easily. Lastly, I painted the stand and the cooking grid with an aluminum paint to make it more appealing aesthetically. Also, I added some soil inside the body and the grill box is finished. In comparison with my original plan, my output was somehow similar yet, it contains different parts that were not mentioned in the original plan. Two of these were the stand and the 2nd layer of metal for the base. However, though they are different, both were still the grill box that I had in mind and it turned out well. IV. Conclusion In conclusion, the final was a fun and learning experience. It allowed me to acquire different skills that are related to my course, also I learned more about the importance of designing a product. The lessons from this subject helped a lot in canvassing the materials and equipment needed for this activity, as well as knowing the importance of safety in doing such activities. Though I made changes in the actual making of the grill box, I am still satisfied because it came out well and durable. I realized that these activities drain a lot of energy which made me appreciate this course more. Lastly, I need to practice more in designing and making a product based on the design in order to have more experience and avoid such mistakes. Also, this will help me improve as an aspiring engineer. V. Post-Credit: a. I would like to acknowledge my mother for contributing for the expenses of this project. b. I would like to acknowledge my uncle for letting me use his equipment which really helped me in making the grill box. c. I would like to acknowledge our former ‘boy’ for teaching me how to weld and assisting me during the making of the grill box.
