In Week 2, Civil, Mechanical, and Industrial Engineering were covered.

Civil Engineers design, build, supervise, operate, and maintain construction projects such as roads, building, bridges, water supply, and sewer treatment. They are crucial to construction industries (ex: ship building, power) because they plan and supervise as construction managers. In addition, they make sure a city's infastructure is operating well and modify it to keep up with environmental/human demands.

Mechanical Engineers design, develop, build, and test mechanical devices such as tools, engines, and machines. They use the principles of motion, energy, and force to create new devices.

Industrial Engineers find ways to eliminate being wasteful in production. They make devices in order to integrate workers, machines, information, energy to make products or provide services.


 First, we learned about the different types of bridges. These bridges include arch, cable stayed, suspension, and truss bridges. We learned that truss bridges are the strongest due to the triangular shape. We did a few activities comparing square structures and triangular structures, and indeed triangular structures were stronger.

Our task for the Bridge and ROV project was to build a remote control car from a VEX Robotics kit that was capable of carrying 3 standard red bricks. We also had to create a 4 ft balsa wood bridge that would support this car as it travels across. The car had to autonomously turn itself around or be controlled by a remote. We had many requirements, such as the dimensions and materials limit.

Next, we experimented with the West Point Bridge Designer 2016 Software to create our bridge. When using the software, we had to stay within certain requirements, such as placing the deck 12 meters above water, using standard abutments, medium strength concrete, etc.

After, we began to construct our bridge. We had to cut the balsa wood precisely and glue it into place, while making sure the bridge was sturdy enough to support the car carrying 3 bricks. At the same time, half of our team began creating the robotic car and programming it to be autonomous and remote controlled.

 Then, we created a scale drawing of our bridge design. Another group created a model of our bridge to check the accuracy of our scale drawing. The scale model looks different because we had a different initial design. Nonetheless, our scale drawing translated well into a scale model.


 In the end, our bridge held up the car with 3 bricks!. Our car was not as successful, as the back of it was dragging, making it unable to move smoothly or quickly. Our group also held the record for the brick test! The bridge was able to hold 11 bricks before breaking. The videos are linked down below.
