Simple but according to my searches a very under utilized tool. Using pendulums hanging from the roof of a vehicle to help you guesstimate the g forces being put on the vehicle. As an example hang a perfectly balanced pendulum from your rear view. When you accelerate it will pull back. Turn left hard enough and it will swing right. On long turns it will stay at a certain angle depend on the g forces being applied. I personally find it a great and cheap way to learn your vehicle. What are your thoughts ?

 

Slightly harder to acquire but the theory is one in the same.

 

WHERE THE F IS THE LIKE BUTTON!!


Dude, OP, you forgot that when you brake, that perfectly balanced pendulum will break (your windshield) also. You plan on transporting tofu? Did you forget to fill your cup of water?

Why not just get an accelerometer app for your iOS/Android device? That way you could have real time feedback, and not have a piece of metal flying at your head/windshield/girl's *****.

 

i honestly don't think a pendulum is a safe thing to utilize as a Gforce indicator for the reasons above.
Besides that... when would you have any time to really look at one while you are driving?
Useful tool? Nope.. accelerometer yes. the app store has endless options.
Or you can buy an in car data acquisition system that will do everything for you and not cause you memory loss or embed itself in your window.
Maybe if you use a tennis ball attached to a string it might give you some placebo effect of a pendulum?
I commend you for your efforts but the danger negates the need for what you describe.

 

Buy an AiM Solo and KNOW your G forces...

 

Digital methods of reading G forces are the ultimate yes, but we dont all have that money. As for knowing the G forces the pendulum is the tool to learn.

I personally have never had problems with it hitting the windshield but i drive a Del Sol and the windshields extreme angle prevents that.

All i can say is dont knock it till you have tried it.
Looks nice too..

 

Do you have a phone? There are programs that do that and much more.

 

Please do explain how having a weighted trinket is at all helpful in estimating the 'G forces' versus downloading a free app which will actually give you viable information?

You might as well just go around a corner really fast, and take a guess at how many G's you pulled.

Or if you want to do some math

Find your acceleration (A)
A = v2 /r

A= acceleration

V=velocity (your speed) [squared]

r=radius of the turn

plug in the numbers:

Say you were going 100mph around a turn. Since you need to convert MPH into FPS you'll need to multiply it by 1.466666. You need to use FPS due to the fact that you aren't going miles in a turn. That'd be 147fps.

Say the turn was 500ft.

Plug it in you get:

A= 147[sq] /500

A=21609/500

A= 43fps/squared


Find how many G's you pulled:

Divide A by 1G (32 fps)squared

G=1.81

Anybody want to correct me? I think my math might be a little off..I'm a bit rusty..



OOORRRR

Just download that lol.

 

harry's lap timer...its a $20 app. get a windshield car mount...it gives you all that info(lap times, section times, g-forces, etc) not only that it will it record a video of your lap it gives you the option to overlay that video with said information

example....im a noob don't hate on my driving to bad (also got a new phone and didn't hae a car mount so I just ziptied m phone to the old mount which caused the video to be a bit shakey)

 

An undamped pendulum as a tuning tool is kinda retarded... and the idea that you can look at/measure where it is while on track is even worse.
