For my Wednsday Robotics Project Group. Here's a little 3D printing project that I think you'll enjoy! It uses Fusion, rather than Inventor. I'll show you how to install fusion in class (for free if you're registered with Autodesk as a student). Here's a link to the drawing which has the key dimensions: a360.co/3V09i1R

Here is the tutorial I promised you in class. Links to grabcad model files mentioned in the video: - grabcad.com/library/hobby-motor-3v-1 - grabcad.com/library/0-5m-crown-gear-1 Two things I forgot to mention in the video: 1. You can easily change the number of teeth of the compound gear - ask me how! 2. I forgot to make a joint between the motor and the chassis. Use a slider joint. Ask me how ...

I need this training. Thank you.
THANK YOUU, its the school holidays and my drafts due 1st week back and I had no clue whether it was absolute error, percentage uncertainty, percentage error or absolute uncertainty that was meant to be the error bars great explanation for why we normally exclude the vertical error bars too!!
Good beginner video ty
Glad it was helpful!
Hi can you post a video regarding crown gear model making
Thanks for the videos, very informative
God math has never been my strong suit. Ok, the rocker in space is actually relevant to the topic I'm interested in. I'll explain the issue. I play Star citizen a space sim game. They've implemented a G force mechanism that causes you to black out. I argue this is unrealistic. Most ship speeds in the game are in meters like 1000 meters. I'm unaware of whether it's meters per second, meters per second squared, or just meters and hour. (I suspect it's meters per second.) Seeing as most people black out at 4-5Gs, I figured at 50 m/s squared you're blacking out. However, at 1000 m/s squared, you'd be liquefied. However, this is meters per second squared. Could you give examples for other units of measuring speed like mph and meters per second?
Hi @kazzdevlin5339. Its not the speed (m/s) that determines the g-force you feel, its the acceleration (m/s/s or metres per second squared). This is, how quickly your speed is changing. If you went from 0m/s (speed) to 100 m/s (also a speed) in, say, 3 seconds, that means your speed is changing at 33.3 metres per second every second. In other words, your acceleration is 33.3 metres per second per second. So that woule be a bit over 3 "g"s of accleration. (33.3/9.8). If you went from 0m/s to 100m/s in 2 seconds, your acceleration would be 50 m/s/s (ie: speed changes 50m/s every second). That would be approx 5 g of acceleration. (50/9.8=5.10 g to be more accurate. Does that help?
@ianthompson4882 So if i state 1 M/S^2 would achieve the speed of 5 meters a second in 5 seconds or 10 meters in 10 seconds or I'm I way off? The time factor is critical, @ 100 m/s in 2 seconds, feels like 5g, but at 8 seconds, it may only feel like 1.3g? So, in the game, these ships are going 1000 m/s. Let's say it takes 15 seconds to get to that speed that's close to 7 Gs whereas two seconds, nets you 51Gs and a really big mess? To further complicate this, let's say we're in space no air, no friction. Nothing to slow us. If I were to fire the thrusters only on the left side of the ship, inducing us to spin right, does this exacerbate the G-force effect? Our initial heading still remains the same, but we're effectively facing in a new direction.
@@kazzdevlin5339 You're on the right track with your 'translational' (straight line) motion examples. ...and you said Maths wasn't your strong suit! ;-) Spinning complicates matters. When you spin, centripetal acceleration is involved. Turning is a form of acceleration, because your velocity is changing (even though its the direction of your velocity, not the 'speed' of your velocity that changes. But ts still a change in velocity, and still involves acceleration) I'm sure you can imagine when you're on one of those amusement rides that spins really fast and you feel pushed outward. That outward 'push' you feel is not actually a force, it's your inertia trying to resist the centripetal (rotational) acceleration. Your centripetal acceleration depends on how your tangential (rotational) speed AND your distance from the centre of rotation. the formula is a=mv^2/r So if you're accelerating in a straight line AND spinning, you need to vector-add the translational (straight line) acceleration to the centripetal (rotational) acceleration. The divide your total acceleration by 9.8 to get the 'g's you'd experience. Does that make sense?
@ianthompson4882 Moral of the story: If you went from 0 to 1000 m/s doing 7Gs, turning is very bad. Wanna thank you for all the help much appreciated
Good work Mr Thompson
Thank you kindly
Any changes recently? It does not show the "align" when I right-click!
Each line needs to have only equation on it. If there are any other characters on that line (even a space or a tab) on the line, it stuffs up the alignment feature.
🌹 "Promo SM"
Flies beautifully!
Thanks a lot! At 3:57 you can see the context menu. It shows "Align at =", and thats a short cut for doing it in one click after you have marked all the lines in the equation :)
life saver
Mfcker sounds like a cowboy. Are you from Texas?
wow
Thanks sir!
Thank you so much! Note for others, this also applies in Excel. I had to redo the Shift + Enter thing a few times before I got it to work though.
Thanks for the great video series Ian. Is Inventor free to download?
Students and teachers can register for a free license. www.autodesk.com/education/edu-software/overview?sorting=featured&filters=individual If you're NOT a student or teacher, then its actually REALLY expensive. Like, thousands of dollars each year. But it's very, very powerful and heavily used in industry. I use Inventor for all my educational stuff (using my Teacher license) and FreeCAD for anything commercial I do.
btw. hope you're well mate!
Nice flyer!
Never told me he was an internet microcelebrity...
Hi Ian, these look great. I have just sent an email to my Science HOD requesting six of these. Hopefully you will hear from him soon. Did I tell you I have inherited a year 12 Physics class this year? Hope you and your family are all well.
Thanks Phil, much appreciated. I hope you find them really useful. We're all well, hope you are too! Enjoy teaching Physics!
What I need is to detect the magnetic field produced by a hidden camera.
Hi Richard, Unfortunately this is probably not the sensor you're after. It's designed for high school Physics experiments, not for industrial applications. But thanks for watching!
Thanks for this video Ian. Very informative and easy to understand.
Thank Rohan - hope you're well mate!
Excellent and valued resource, Ian. Thank you for making these videos.
Thanks! I'm very pleased they are useful.
THANK YOU SO MUCH
Ty mate
Absolute champion! Lucky kids!
You're a legend of a teacher. What a great little rig.
Reminds me a bit of the ping pong launcher. After watching this, I guess I’ve got to make version 3 soon
It's a lot like the ping pong ball launcher! Hope you're well :-)
In America we simply call this bullet drop
I'm a bit jealous you didn't do this with your Year 11s in 2017
Hey Kieran, good to hear from you. I hope you're well!
Btw... your bike powered ipad charger was pretty cool!
Great video, I really enjoyed watching this, thank you for your efforts 😊
How do you add the individual error bars? :)
delete the graph and try do it again, and if that doesn't work keep deleting and trying
thanks mate! physics assignment due tomorrow and I had no clue how to do this until after this video
same bro
thank i needed this much help thank facts
lol
Love Ya Mr Thompson!
Absolute legend bro ur helping me more than my actual physics teacher senior year at KGSC
Bro what teacher you had?
cuz you should already be able to do it. evidently i don’t know either cuz i’m here but i’m aware of my mistakes
hell yeah man nice
thank you nice video it helped me
Any way to align at two points? It seems the answer is "No".
Great explanation.
Wow it was very helpful to understand. Thank for great explanation ❤️
Hey thanks for your excellent explanation, helped me alot. If I would like to calculate the forces acted on the person in ruclips.net/video/VKcmgPTKLMI/видео.html Do I need to multiple the g- force by the mass of the person? lets assume he weighs 100Kg, so the person will feel a force of 480.2 N?(0.49*9.8*100=480.2) And about the first example of the rocket, if there was a person in it and there is gravity. How should I calculate the forces acted on the person in this example? becuse the acceleration of the rocket is horyzontal and gravity is vertical.
Thank you so much
Thank you for this absolutely beautiful explanation. This video should be the first one that should come up when looking for 'GForce'! Great video..thank u
THANK YOU VERY MUCH!
