Introduction

Maryland engineering challenges have evolved into a number of competitive learning opportunities as a result of the work done by engineers, educators, and people associated with the Baltimore Museum of Industry.

My designated task is to build a 1:120 (1 inch to 10 feet) scale model off bulk carrier cargo ship. The goal is to use the radical thinking and engineering skills that has been learned over the recent years as well as the skills that are being picked up along the way to successfully build this model cargo ship while maintaining the criteria guidelines given for the project. At the end of this project the groups wants to build this cargo ship and make it fully functional and to win the competition as well. In order to complete

this challenge with the most successful outcome, the group must complete the construction on the boat within the time allotted and staying in the constraints of the criteria.

The requirements for the boat include being made of a single hull made of a rigid material, using a 12-volt electric motor for propulsion, not exceeding the length limit of 60 inches, not exceeding the width limit of 15 inches, not exceeding the maximum drafting of 4 inches, and having the depth of the hull. The boat must also be marked for identification, have the ability to hold eight 5-pound bags of sugar, and show sufficient stability when loaded to simulate an actual fully loaded, operational cargo ship.

Cargo ships have always been essential for society's daily operations, even predating modern inventions like smart computers and touch screens. Back in 1902, the German Pressures held the title as the largest sailing ship, regularly traversing between Germany and Chile on a voyage spanning approximately 13,200 km. It would take the ship anywhere between 58 to 79 days to complete the journey, with its highest average speed reaching 15.8 MPH ("Cargo Ships"). While the record for the biggest cargo ship remains unbroken, advancements have been accomplished in different aspects of ship construction, particularly in terms of efficiency.

In 2009, the Eugene Markers became the longest ocean freighter with a length of 1,300 feet. Although it had the ability to travel at around 30 MPH, it only cruised at a slow speed of 11.5 MPH ("Cargo Ships"). Cargo ships have existed since ancient times, but their significance lies in their modern contributions.

Cargo ships were not utilized for transportation until the A.D

time period and encountered issues like piracy and robberies (Hitches, 2010). Nevertheless, as society acknowledged the advantages of ships and various regions implemented their own regulations, there has been an increased emphasis on enhancing technology and comprehending the construction of bulk carriers for global improvement. This project highlights several aspects which include a written report, an oral presentation, the sign and fabrication process, reliability, and performance demonstration. The competition necessitates submitting a written report that outlines the design process, boat construction, and testing.

Summary: To successfully construct a cargo ship, one must have a comprehensive understanding of its definition, functionality, significance, origins, and the construction process. Cargo ships serve the purpose of transporting goods globally and contribute significantly to one-third of international trade. Although they have existed since ancient times, their role in society has evolved and continues to drive shipbuilding advancements. The choice of materials is integral to the ship's construction, just as much as its design.

The material chosen for this specific boat is fiberglass. Fiberglass is being incorporated into the construction because it is an ideal solid material to add to the outer shell, protecting the model in the harsh conditions of the testing area.

Design Proposal

The first design proposes using milk crates for the boat's inner shell and fiberglass for the outer shell. This design would ensure durability, allowing both shells to withstand the weather during the contest while in the water. It would also provide strength to support the cargo's weight. However, the combination of crate and fiberglass materials may make it challenging to mold the boat into the desired shape and greatly constrain the structure's

measurements.

The second design uses foam to construct the inner shell and fiberglass for the outer shell of the boat. This design enables easy molding and creates a lightweight boat, potentially resulting in faster travel. However, there is a concern about whether the foam can bear the weight of both cargo and support the model. Conversely, the third design utilizes wood, most likely plywood, for the inner shell and fiberglass for the outer shell.

This design is intended to reduce the difficulties of designing and shaping the inner shell, while also ensuring that the outer shell has sufficient strength for support. However, using wood as the material presents some challenges. Wood has a tendency to absorb water, which increases the boat's weight and slows down travel. Moreover, there is a concern that wood may not offer enough strength to maintain the model's integrity.

Analysis of Errors

Throughout this project, various errors were encountered.

Initially, there was a delay in acquiring the essential equipment required for constructing the cargo ship. Mr. Dulcet and the team members lacked clear communication regarding who would be responsible for purchasing the necessary supplies for the vessel. Additionally, there were multiple errors during the cutting of the wood, resulting in uneven edges. Consequently, we had to spend additional time refining the wood to ensure proper fitting of all the pieces. Overcoming these challenges has proven to be quite problematic.

The testing process has experienced significant delays because of this issue. In the comparison between pre-post designs, the initial plan was to use a stronger adhesive for combining the inner wooden shell. However, due to financial limitations, we had to choose whatever adhesive was accessible, which happened

to be hot glue. Furthermore, instead of utilizing a thick inner shell as originally planned, plywood was selected as an alternative.

This would result in a lighter boat and increased speed. The Programmer's Project Evaluation has taught me that for the boat to be efficient, we need to find suitable materials that can securely hold everything in place and allow for water travel. These materials should be strong enough to support the cargo while still being lightweight enough for fast movement. Ante and John are currently drying the resin and fiberglass by taking the boat outside. Additionally, John is measuring the boat's height in preparation for applying fiberglass.

Ante is starting to pour resin on the boat. The boat's length is 60". The travel time is 182 seconds. The distance traveled required the freight rate formula (Length + Time) / (Distance x Cargo) = REF (60" + 182 (4 x 40 lbs.)). The required freight rate is 1.5125. This data shows the results of the required freight rate (REF) after the Cargo Ship underwent testing. The graph above shows the boat's efficiency when carrying certain percentages of the cargo. Chapter Five: The Conclusion. Chapter Five discusses the purpose of the Maryland Engineering Cargo Ship Challenge, which is to design a 1:120 scale radio-controlled model bulk carrier cargo ship that must transport eight solutions for the transportation of goods on a cargo ship.

Firstly, the team engaged in thorough discussions regarding the preferred design of the cargo boat. Subsequently, the boat was constructed and later the motor was incorporated. Ultimately, the boat underwent testing in a lake, both with and without weight. In conclusion, the main hull has

been constructed, and the team is presently completing the motor and steering system for the boat.

We will abandon our project to allow next year's seniors to complete it and participate in the competition due to the lack of sufficient time. Moving forward, the team should assign specific roles to each member to prevent confusion and avoid wasting time for those unsure of their tasks.
