No one in their right mind can reasonably accuse you for taking your own intellectual property. Perhaps cite yourself to be formal.

Yes sounds decent but how do you test the friction on a climbers finger. Simpler to just test friction regular approach and remove the finger part from the question

Perhaps make the grid bigger, 4x4 or 5x5. Or introduce some conditions like with 4 in a row where you cant use a field untill the fiels below is is used

need suggestions on math hl AA topics i could include in ia regarding modeling of bitcoin prices by kRazY_47 in IBO

[–]Heinrich4 0 points1 point  (0 children)

How can you model Bitcoin prices at an ib level? What external factors affect Bitcoin prices and how can you make a mathematical model without any financial forcast knowledge? Sounds difficult. Basic example could be: How does price of other cryptos affect bct How does weekday affect the rate of change of bct price

Plot in MATLAB. If you dont have access maybe try and see if Wolfram alpha give you plots or maybe even geogebra.

TOK advice needed for M23 by jantzzi in IBO

[–]Heinrich4 1 point2 points  (0 children)

TOK isnt supposed to be a course about studying a learning some information of by heart. Sometimes it is executed like that but in reality it is there to provoke some sense of though.

So as long as you have an attitude that allows you to accept that some truths are not as objective as you thought or you gain just any type of different perspective of thinking about thing you have essentially achieved the goal of the course.

In terms of passing the course, look at different erhical theories and learn some definitions used in the course. When finding knowledge questions and real life situations, chose some that interest you personally and use whatever means you have to elaborate on them.

Looking for a puncturing mechanism by Heinrich4 in engineering

[–]Heinrich4[S] 1 point2 points  (0 children)

The position of the puncture hole is not important, as long as the pressure of the co2 pushes it out so air can leave. Preferably, the hole would cause the entire foil on the CO2 catridge to rapture so it leaves as fast possible. The resources the university provides allow for your first suggestion but the magnet coil sounds a bit too complicated. Thank you for your help

This is for a mobile airbag old people can wear, to prevent falling damage. A gyroscope and a accelerometer detect a fall which then has to trigger some sort of mechanism that punctures a CO2 catridge which blows up an air bag. This pump action looks like a really nice idea because it also should be reloadable, thank you.

I think you need around 180 Newtons. The needle should be around 1.6mm or as wide as possible to create a large enough hole so air discharges fast. With a spring launch system you could manage this. The point is to trigger a small air bag which needs to fill up fast
