One day project: Tony’s Roller Coaster race car

One day project: Roller Coaster Car

Goal:

Pass the roller coaster track

 

Design process and how you built car:

I will build the car low so it decreases the resistance of the air. I will use heavy material to build the car because the gravity makes the heavy car go faster down the track.

 

Materials:

Axles and wheel:

Wood, paper and glass

Tools:

Cup knife, Scissors, hacksaw and cutting machine.

Final Car:

Challenge/Problem you may face:

 

It’s hard to glue the part of the car together so i use a hot glue. The car is too fat. It almost as fat as the track so I build a new thin car. My cars always turn over. I break a lot of part of the car but I don’t know that problem with my car. So I make a new car.

 

How could you improve your design:

I built a new, thin car and I stick a water bottle on the car so the car goes heavier and go faster down the track.

I don’t have time to test my new car so I don’t have the video.

No Limit For Speed

My first design was trying to make a car that was thinner, so that way it can go faster. My first prototype fell, the wheels popped off with a chunk of the Styrofoam and the tip was squished. The car wasn’t usable anymore. Because my first prototype didn’t work, I made prototype 2 which worked a lot better. Prototype 2 was wider and less pointy. I also took the rubber part of the wheels off so there would be less friction and the car would go faster. Some problems I faced was the wheels breaking, and the car not being able to go over the hill. If the wheel broke, I would switch the broken wheel with a new wheel and I would push harder or change something that was holding the car back from going over the second hill. One was I can improve my design is by making it lighter and flatter. Having a lighter and flatter car will make the car go faster. Also I would take the rubber part off the wheels to decrease the friction. I chose this One Day project because I can design a car myself and adjust it so it will meet my goal. Something that went well was eventually, the car was able to go over the hill and meet my goal. Therefore, this One Day was a fun and interesting experience for me.

Prototype 1:

Prototype 1 was thinner and longer than prototype 2. One the first run, the car fell off the ramp and the tip was squished, and the wheels popped off. After some adjustments, prototype 2 still didn’t work and was time to make prototype 2.

Prototype 2:

Prototype 2 is wider and flatter. At the end, I took the rubber off the wheels so there would be less friction against the wheels and slow it down. The car was a lot more successful than prototype 1.

 

Prototype 2 Adjustments:

When I was hot glueing the straw onto the car, there was a hole in the straw and the hot glue reached the wheel axel which prevented the wheels from turning. I had to cut the wheels off and attach it again.

At the end, my car was able to go over the hump and I have reached my goal.

Tom’s Rollercoaster Race Car

My goal is make the car go through the track all the way.

I made my car design like a car that have the least air resistance. I tried making a car that can go trough the whole entire track. I designed my car like rocket and it just ran out of the track.

prototype 1-3

I tested my prototype 1 but it didn’t work. It just fell out of the track and it just broken on the track. and in second time, I got to the hill but my car didn’t have power to go over. i think the car need more weight.

I had a problem that my car broke so I need to build again. I was hard because my car broke and I updated to prototype 1-2 and i got an idea that put the prototype 1-2 in the prototype 1-3 because prototype 1-3 is big. so this work like prototype 1-3 run and while prototype 1-3 is running, prototype 1-2 comes out of the prototype 1-3.

prototype 1

Next time I will improve my design by making the air resistance low, and make the weight high. i will improve my design skill better.  MVI_0208

Kamsen’s Radical Rollercoaster Racer Xtreme

Prototype 1:

For this one-day, I decided to build my own race car for the ramp in front of the FA space. My goal was to build the fastest car in the group and I failed horribly. The car was originally going to be a blue and black Lamborghini that would’ve been really fast, however, I forgot about my original designs and made a very average looking car:

I did, however, decide to improve on it by making the wheels much more stable and I drew some cool patterns on what I dubbed “Kamsen’s Radical Rollercoaster Racer”

After a few tests…IMG_3010

I realized I needed more weight on the car to go faster downhill using Newton’s Second Law, so I decided to add a piece of wood to the front of the car:

Prototype 2:

However, the results of the 2nd and 3rd prototype turned out to be the same, which confused me greatly. After that, I tried taping a bigger item to the car and found a water bottle:

Prototype 3:

Surprisingly, it worked this time. My car didn’t go past the second ramp, but it still got further than the others and I had no time to improve so I just settled on it.

If I had more time, I would have redesigned the car with a sports car-esque design that worked for others.

Overall, this project was not very interesting and could have been a lot better if I had more time, but its only 1-day and I couldn’t get much done in one day. However, I did learn a lot about building and design, as well as the ability to incorporate science into day to day life, which was not something I thought I would learn.

Edward’s Cenrenario Lamborghini

My goal for One Day  is to get over the second ramp and be one of the best

My design process includes me first thinking about a round  car but after thinking about the detail I realized that it will be too complicated and may not work out as good as a simply but durable one. after rethinking  about my design i came up with a flat car which have a wind sheild in the front to reduce wind drag and rocks to have more weight

no photo because of technical difficulties

One problem that I faced was how to add more weight on my car so I can go over the ramp. the solution was to add more layer of wood and some stones to increase the weight.

I would improve my design by adding more weight and a water bottle because more weight means more potential energy.

Goal: I want to build a car that can make it though the roller coaster track

1st Paragraph: Design Process & how you built the car.

At first I couldn’t think of an idea so I went on Google to search up some ideas, this gave me the opportunity to see what fast cars look like and what they need to reach that speed. I noticed that in order to make a fast car you wanted a bit of mass and your car should be quite aerodynamic. Firstly, I needed to make the front of the body. I decided to make a low slope in the front of my car to reduce drag and placed wooden blocks on the car (gluing them on) to increase some mass. Then in the middle I added even more wooden blocks because i knew that the greater the mass the faster it would go, but i knew that wooden blocks by itself is really weak so i covered them with plastic. Before I made the end i decided to go down to test out my vehicle, but after rolling it down I noticed that my car was to fragile causing me to extra glue gun my car. At the end i decided to do the same thing because it made my car quite durable. Adding water bottles made it even faster due to higher mass.

2nd Paragraph: Problems or challenges you may face or faced.

  1. How to make the car go over the ramp
  2. How to make the car as durable as possible
  3. How to make my car to go as fast as possible
  4. How to make my car stay on the track

3rd Paragraph: What Would i change if i made another one

  1. I would add more mass to my car because i noticed that mass effected way more than aerodynamic in this situation.
  2. I would Change the shape of my car because it isn’t so aerodynamic
  3. I would make it more aesthetic
  4. I would make it much lower

Roller coaster

Goal: I want to build the most effective race car for the roller coaster track by testing different designs.

Design Process and how you built your car

When I first built my car, I first used a plastic platform, then cut spaces for the wheels. After that, I added some blocks to the front underneath the car and added some wood/a piece of plastic at the front to make it more aerodynamic and heavier. However, the blocks underneath the car were too big, so when I tried to run it down the platform, it scraped the platform. This led to me trying to remove, and I finally did. After that, I realized my car mass was way too low, so I added a bunch of wood on the car. This was more effective, and the car went higher, but it was the end of the day and I ran out of time.

 

 

The challenges when doing this project:

Original thinking: Some challenges when doing the project is finding the best car (after trying them out) multiple times, as we might run out of time to find the most effective way. Another challenge is that we might fail to build the car.

One challenge was that a lot of times, the car would go off the track and break apart, constantly forcing me to return back upstairs to fix the car. This lead to me wasting lots of time. To fix this, I removed the car tire rubber, making it run more straight. Also, the multiple blocks fall off constantly, so I added duck tape to add insurance that car would stay together.

If you were to do it again, what would you change?

If I could do it again, I would make my plastic board at the front at a higher angle and taller, because after I added the blocks of wood, it was too tall for the original plastic board, so the wind would just hit the wood straight on, instead of hitting the plastic board and going off at an angle.

Need for Speed

On One Day, I participated in the rollercoaster group and created a car that was supposed to go over the slope. My goal was to build a race car that could go fast enough to go over the slope. I chose to do the rollercoaster group because I wanted to do some engineering and learn how to use different tools.

I started off my design process by researching the aerodynamics of a car from http://www.buildyourownracecar.com/race-car-aerodynamics-basics-and-design/. Next, to give me some inspirations, I searched for gravity cars on google and chose some models to base my car off. I started off the building of my car by making all my measurements and drawing a quick model on the table to give me a basic idea of my car. I then drew out all the sides of my car with a pen so when I cut it with an exact-o-knife it would be straight and exact. To put my pieces together I used hot glue. After my first try, my car broke so I needed to fix it. I just fixed the wheel back on and tried again, but it didn’t work again, so I needed to take another plan of action. I changed my wheels and took off the rubber around it so it was sleeker and could go faster. I then put on a fin on the back because there were many examples of gravity cars that had fins.

Some of the problems I had was my car didn’t run straight, it wasn’t heavy enough, it kept falling apart, and it wasn’t fast enough to get over the slope. To solve my problem of my car not running straight, I realized my axels weren’t straight, so my wheels went in different directions, making it move diagonally. When I first glued my wheels and axels on, I used a lot of glue, so when I tried to take it off, they were glued on too hard. To solve that, I just cut off the edges of the straw and got new straws to make new wheels and axels. To make sure I placed them straight, I measured with a ruler to make it even on both sides so both sets of wheels would be parallel to each other. When my car wasn’t heavy enough I glued on six rocks onto the inside of the car. After I finished gluing four rocks, it was a bit heavier on the left, so I had to glue on two more rocks closer to right to balance it out. My wheels and sides kept falling apart, so I used duct tape to make it more secure. The duct tape was really effective, because when my car fell of the tracks it didn’t fall apart anymore. My car couldn’t go over the slope because it wasn’t fast enough, so I searched for gravity cars with fins, because I was advised to try fins on my car. Then, I saw many people took of the rubber off their wheels, and when I tried rolling my car with them off, they seemed to move a lot faster, so I took off the rubber. When I tried my car with a fixed axel, rocks, a fin, and no rubber on the wheels, it managed to go over the slope.

I think next time when I make a gravity car, I will put less hot glue because it was a big challenge for me to try to take pieces apart and if I put more hot glue on the sides of my pieces to make it stick better, it took up more space, so when I tried to take it apart and failed, it was harder to fix my problem. Also, if I do it next time, I will duct tape my rocks to the car, because the rocks that were hot glued came off inside the car. The problem was, I couldn’t fix it and stick it on again because I would have to take off the top, and it was secured tightly with duct tape, so if I took it off, I would probably rip my car and would have to start over again. The rocks made it slightly more difficult for my car to go over the slope because it messed with the car’s balance.
