Formulae Dealing with Inertial Force

Does the class that spawns these questions have a name?

Why can't the instructor give it to you?

If their intent was to have you research the subject and find the formula, having it given to you would cheat you out of the experience of performing independent research.

Maybe you are just curious?

BTW, #1/2/3 are all acceleration forces. It doesn't matter if you are speeding up, slowing down or turning the formula will be the same, when you find it.

Hey there, lynlynch.

Are you certain that forces for cases 1, 2, and 3 are the same? For car on side...

...is the force not 9.8N?

Perhaps insufficient force applied to brake pedal? Ahh, this auto has disc brakes.

This is a case of friction overcoming inertia and acceleration giving way to gravity.

The objective behind this question is to find out the forces acting on an object inside a vehicle relative to the vehicle..

Because.. i m doing a ppr work on vehicles for the physically challenged.. where a wheel chair is locked suitably inside a driver's cabin .. i want to know the forces acting on the clamp that would hold a wheel chair inside a vehicle in motion..

pls help me with concerned formulae.

Let me under stand this. You are doing a paper? Or are you "designing" a restraint system?

If what you are doing will ever be applied in real life, you are not the correct person for this task.

Is this homework?

I m actually designing a mechanism to lock the wheel chair...

Well.. this will be applied to real life as well.. and right now i might not be good enough to make one...

thats y i ve submitted this thread... so that i can gain knowledge abt it...

but i m sure.. what i design will never be futile... results will show...

it will be good of u if u can help me with exact formulae...

again... my question is clear... "formulae to calculate forces acting on a body inside a vehicle, relative to the vehicle."

Giving you the formula, if I knew it, would be like giving a loaded gun to a small child and telling him to go play. Both scenarios are potentially lethal.

Get an engineer to help you with the "design".

No probs lynlynch...

keep ur gun to urself...

i ll get to know wat i need to...

Thank u for responding!!!!

Regarding the denial of a class project of some type:

Regarding the formulae request, there are many, many place to find such:

http://en.wikipedia.org/wiki/Banked_turn is a place to start. Have at it.

Thank u for both the links!...

The first one was refreshing though ;-)

Why don't you post your work, so far, and we'll take a look at it?

I assume that you have something tangible to show us?

I have put my gun back into my shoulder rig. For those who don't know what a shoulder rig is:

We had a saying back on the farm, "Don't let your alligator mouth over load your Humming bird A*s."

Cheers.

Well, if he posts his work here, his classmates will be able to copy!

Ah, well... anyway, the link I gave him will be of limited direct value. If he does read it carefully, he should be able to find the rest of the stuff he will need.

Happy trails to you lynlynch.

i m unable to load my works as of now.. so far wat i ve done is on paper... rough calculations... regarding the clamp details.. thickness of plate, clamp lever diameter, n so...

for these.. i have taken the max. force acting .. based on the inertial mass of the wheel chair... and accordingly calculating the max. deceleration acting on the wheel chair during braking... which will appear as tensile stress in the clamp at the rear of the wheel chair, holding it to the cabin...

and for ur info... this is not my homework... just a practice project to understand designing to a good extent.. so no problem of copying or other stuffs!!!

The issues involved with this design problem have already been solved. Check out:

ThanQ... but i have gone through this site before... i m not interested in buying a lock but in fabricating one through design...
