Car Transport Evaluation (Individual Electronic Assignment)

1. What did you learn about the design of your car and the ability to cover 4 meters?

I found that my design was good enough to go exactly 4 meters and a little bit more!

2. What materials should go into a car and why?

Big wheels which gives it more distance.
stable wheels so that it doesnt slow down car.
hook screws to attatch to axel so that wheel moves freely.

3. What is important to know about

a. the wheels of the car?

if it is strait, alligned, stable, and not wobbly

b. The mass of the car?

it is light and not heave

c. The length of the car?

a short body leaves the rubberband with not enough pull to make the rubberband work and a long length doesnt give the rubberband enough room to wind up the tire.

d. The steering of the car?

that it goes strait for maximun distance

4. What would you do differently next time?

Make my big tire alligned with my bosy and other wheels so that it goes in a strait direction and change the screw i attatched to the rubberband becuase somethimes it made it so that the rubberband doesnt leave the screw.

MTV Lab

Title: Need For Speed

Purpose:
1) To create a vehicle that can go further then 4 meters with a mass on it.

2) To Have a better understanding of DVAT.

3) To Find an gas Alternative.

4) To see the work of gravity.

Apparati:

Theory: Motion!


Pictures:

Method:

1) Looked at web links provided by Mr T. and filled out online internet form. (as seen in earlier blog)

2) Created a Blue Print of MTV. (as seen in earlier blog)

3) Gathered Materials for prototype.

4) Built Prototype. (as seen in earlier blog)

5) brought protoytpe to Mr. T for inspection.

6) Made changes to Prototype. (as seen in earlier blog)

7) Raced against table and made it past 4 meters.

8) Raced for final Race and lost!

Data Table:

Race with Table 4

Race with Other 4 mater cars

Finals!

Joseph Tariga's MTV!

MTV Self-Evaluation!

Mass
6
The mass stayed in the same place during the whole race!

Construction
6
My car had an original design and was very creative with the use of PVC pipes, water bottle caps and three wheels! Car was complete!

PE/KE
6
My rubber band powered the car to go a great distance and once the rubber band was off it kept moving! My car was at a fast and steady speed!

Rubber Band
6
My rubber band did not snap and ran properly!

Parts holding together
6
My car was stable with not moving or vibrating parts the entire time!

Steering
4
My car had a slight curve to it but was still within the track!

Distance
6
My car exceeded the 4 meters and went 4.3 meters! Yes!

Finished!

The 1st prototype the body was wobbly so we had to redo it!

the front cd wheels were wobbly also!




so i drilled half inch dowels throughout the body(pvc) which made it a whole lot stable and i changed the front cd wheels to some small wooden wheels!


This is the Final Product!
I call it the MACH FOR(Frame Of Referance)!

Construction of prototype

I used a circular wood made for placks because i needed a Big back wheel

I drew lines around the plack to figure out here the middle is and sarted to drill a little bit
I started to drill all the way threw
This is what my back wheel looked like after i drilled the hole
I used my old PVC pipes from the battle of the bands proj. as the body of my car
i fgot a 1/2 inch thick dowel
I cut pieces off for my front and rear axel for my wheels
This is the piece i cut off
i then attached it to the rear wheel

i used a 1/2 inch drill
i then drilled holes on the front and back of the PVC pipes to hold the dowels
I had to make it bigger to make the dowels spin freely
for the front i drilled all the way since i was using two front wheels
