Are thease called torsion motors? They can be made with big springs to run stuff. They genrally have the trobble that retentioning the motor takes soooo much energy and they loose power as it unwinds.

 

Sorry to state the obvious and im not trying to be patronising but be carefull as mousetraps easely break fingers.

Haha! thanks for the advice. i've had my share of un expected snaps on my fingers. not the greatest thing to endure.

are you supplied with the mouse trap? or can you get a better one?

if not, buy two more similar ones and mount their springs on the original trap

a thin spindle and big wheels make for longer travel on flat ground with less total force

 

if you have access to some sort of lathe, you can actually modify the spindle raduis to different spring tensions throughout the travel, giving you finer control over the force curve in the spring and how that relates to the drive wheels.

Yeah your supplied with one, and we were only allowed to use one. :/

Yes. sorry i didn't explain that. the mousetrap is attached to a string which is wrapped around an axle, it's to make the car move. not to catch a mouse

NO, it is impossible to program or make something which is more intelligent than us because it will be based on our knowledge........

[an obvious overlooked fact]

 

you cant create something more clever than you, if it is based on your brain!!!!!

 

but it is highly possible to have AI which thinks quicker, that is possible, already, computer calculators are quicker than humans! just not cleverer, because it was based on be-known knowledge!

It doesn't matter matter if it's based on our brains, theres nobody who mastered in creative writing, mechanical engineering, history, Music and Arts..so on.. but yet, with a Computer, there is an unlimited amount of learning that can be programmed in to it. Now then again, I doubt that a computer could come up with theory's the way that the human mind does. They simply don't have the creativity that we do, and that's something you can't program in to a computer.

I was recently confronted with the challenge of making a "mousetrap car." The rules were simple, make a functional car using a few slabs of balsa wood some copper bars used as axles and CD's as wheels (and of course a mousetrap.) My group used a fairly simple design, simply cut out 3 pieces of balsa, two were long rectangles, about 2 inches by 10 inches. these were put on the sides of the car and glued to a 4 inch by 8 inch piece of balsa (which was put on top of the car, so it had a top and two sides, the top did not fully reach the length of the sides, we then had the idea of using only three wheels, we assumed that in the front if there was only one wheel, the weight on the axle would be less. (which would reduce the friction between the axle and the balsa. The cd did not fit in the middle so we had to cut out a rectangle from the 4 by 8 piece of balsa to make room for it. the back wheels were simply put on the sides so no more cutting was necessary. We glued the mousetrap to the platform we had made (the 4 by 8 piece of wood) we cut the rectangular bar on the mousetrap (the part that "squashes" the mice) and added a copper bar to it to extend the reach, we were hoping this would increase the distance the car could go. we then tied a string to the end of the bar we had attached, and tied the other end to the trap. when setting off the trap, the car reached around 10-15 meters.

I was just wondering if anybody else had some ideas for the car, or if you have made a successful car, and how you designed it. Thanks.

you can't do that because .1111111111111111infinity isnt 1/9 it approaches it, but it never is actually 1/9

 

The proof with the x=.99999

10x=9.999

I dont believe that you can multiply something with infinite numbers by ten, because it would almost be like adding a number, a number would just appear....for some reason it just seems illogical.

Yes i agree it seems illogical. but all these formulas add up . and sure you can add something with infinite numbers by ten.

just imagine

setting it up like you set up any multiplication problem

10

.9

9

so therefore

10

.99

9.9

and...

10

.999

9.99

and so on...(which would be 9.9999 infinite)

So if ive got £10,999,999,999,ive really got £11,000,000,000.Somehow it seems illogical 0.999=1,

We know from primary school that another integer is required.

Why all the maths to 0.999=1

When its 0.999+0.001=1

I believe that using the equations in this topic as is,will not yield a correct formula for calculating distance in regards to our universe.Math is fine as it is without leaving out integers.

no, .999999999 doesnt equal zero

.999999 repeating does.

you seem to have forgotten the infinite after the .999......

So think about it. .33333333 repeating equals 1/3

1/3 times 3 equals one.

.33333333 repeating equals .9999999 repeating

therefore, .9999999 repeating = 1

..in theory..
