How can I determine the center of mass of a vehicle?

ummmmmm that's the prob that friction exists and we have 2 b as exact as possible so v have 2 consider friction

I still don't see any point in taking friction. Secondly, I don't have the wildest idea that how will we calculate friction in our case( I am even confused that while the car is in horizontal position with no external horizontal force acting over the platform the friction is acting or not !). Its definitely not limiting. Thirdly, we have to give a 'standard procedure'. With friction involved it won't remain standard as we would need to know the different values of \mu for different contacting surfaces (tyres and platforms).

if the higher pair of tyres is supported on a sloping surface, then the friction will spoil the equations.

So it is important that the higher pair of tyres (or its axle) be supported on a raised horizontal surface.

This situation can also be simulated by hooking the front end of the car (from bumper or something) and then lifting.

Hi Altairs!

Yes … provided you ensure that the rope is vertical once the car is raised!

Though there is a practical problem … I don't think there's anything at the front of a car that's strong enough not to be damaged.

Something can be attached as an extension to the front side and then the it can be hooked.

i don't get how ur trying 2 remove friction...

 

[Altairs]

How are we supposed to calculate the friction present ?

By fixing it so that the friction is zero, which means supporting the wheels on horizontal surfaces, or the towbar on a vertical rope.

That is exactly what I thought (post 62).

4F_{s} = 0 (fixed and no external forces present horizontally)

Hi Altairs!

(btw, don't send a Visitor Message if it's important, since there's no notification of Visitor Messages, and I might not see it for days. Send PM if you think I've missed a post.)

Yes … ignore friction …

… your post #62, replying to Whatevr, was completely right (which is why I didn't comment on it).

ok so can u tell me how do we calculate the z-distance i.e. the height co-ordinate. we can get both the horizontal distances but wat abt the vertical one??
