Bank Curve Problem: Normal Force on Moving Car

[oreo]

Is normal force on moving car on a track a component of weight or vice versa.

 

[Maged Saeed]

Because the centripetal force is aiming in the direction of x-axis ,, The Normal Force would be resolved into to components one is equal to the weight of the moving object

 

[oreo]

It means that weight is component of normal force. Is centripetal force directed towards center of circle or towards the axis because these are two different cases.

If you draw a free body diagram of this problem what would you have ,,

the Mg lies on the negative y-axis pointing toward the center of Earth , the centripetal force is pointing toward either positive x-axis or negative x-axis [horizontal plane] , And the normal force would have an angel with the x-axis [which will be resolved into components]

I want to ask that is centripetal force acting towards the center of circular track or towards its central axis(x direction)

 

[Maged Saeed]

To the center of the circle NOT to the center of the x-direction ,, I didn't mean that ,,

:D

:D

If it is then the normal force is perpendicular to the track ( ie perpendicular to centripetal force) then it would have no component providing the requisite force. Here is the figure in photo.

Actually what you have drawn is somehow mistaken , The centripetal force direction is a horizontal line from the moving object to the center of the circular track ,,

That was I wanted to confirm
You had first said that it is towards center but if it is so then the normal force would be at right angle to centripetal force as I drew but the figure you drew confirms that it is towards the axis. I took direction of normal force as y- axis.

Okay ,, The picture implies my point And sorry for my English

Thank you for helping me. We done it together.
