Download file to see previous pages Our initial focus will be to discuss the evaluation plan for the construction of the rat trap boat. The evaluation plan will cover the following areas: background, purpose, limitations, questions, methods, instrumentation, time line, and budget. The assignment for the creation of said rat trap boat was initially given in an Engineering and Construction course. The purpose of this project is to create a moving water vehicle that is powered only by the energy stored in the spring from a mouse trap. The following limitations will be set in place: a standard mousetrap, the spring on the mousetrap will be the sole power source, the spring on the mousetrap will be cut and bent, but no heat-treated or chemically alteration will occur, the maximum length of the boat will be 18’ (this does not include the lever arm), all materials used will be non-hazardous, and the vehicle will be self-starting and steer itself.
In an attempt to answer these questions the following methodology will be used to create a rat trap boat. First I will cut the balsa wood into a ten inch by five inch rectangle. Then I will cut one end into a point, making a boat shape. I will then cut a four inch by two and a half inch notch into the other end. Next, I will make four three inch by one and a half inch rectangles out of the balsa wood for paddles. I will then cut the dowel down to six inches. I will then hot glue the paddles to the dowel, making sure they are centered and evenly spaced. I will then allow paddles to cool completely. The next major step will be to wrap wire around the dowel on one side of the paddle and twist with a wire cutter. I will then trim it to about one fourth of an inch to make an axle pin. Now it is time to attach a one inch wire in a loop to one side of the back of the boat shape by hot-gluing one end to the top of the wood and the other to the bottom. I will then slide the end of the dowel through the loop and attach the second one inch wire to the other side, around the dowel. It is now important to place the mousetrap on top of the boat shape on the same side as the axle pin. I will then hot glue the mousetrap in place. Then I will tie string to the axle pin and turn the dowel until I have about two feet of string wrapped around it. I will then tie the end of the string to the “jaw” of the mousetrap securely. I will then set the trap and tighten the string around the dowel. The final step will be to place the boat into the water and release the trap. The jaw should slowly begin to close, pulling the string and causing ...Download file to see next pagesRead More
