Undergrad Frictional Force in Circular Motion
So the frictional force acts towards the centre of the circle formed by the wheels and compared to this circle the centre of mass will be in a direction between tangential component(tangent to the tire) and outward normal -

Undergrad Frictional Force in Circular Motion
But if the tires point in a direction somewhere between the tangential and the inward normal and the frictional force will acts perpendicular to tires, so then wouldn't the centre of circular motion of tires and car be different? -

Undergrad Frictional Force in Circular Motion
So what I understand now is that when turning, the tires point in a tangential direction to the circular motion while the centre of mass or inertia will be in a direction somewhere between tangential and normal. The tangential direction of inertia will help the car move in the circle while the... -

Undergrad Frictional Force in Circular Motion
This does make sense from the reference frame of the observer inside the car but what about the observer in an inertial frame? Instead of centrifugal force force will inertia be acting away from the circle and friction will try to oppose the normal component of the inertia? -
R
Undergrad Frictional Force in Circular Motion
So it seems like when you turn the steering wheel, the tire(s) point in the tangential direction while the centre of mass will be in a direction somewhere between the tangential and the normal. Is that correct? -
R
Undergrad Frictional Force in Circular Motion
But how does the contact between the tire and the ground create a frictional force which is always towards the centre of the circle and not any other direction? -
R
Undergrad Frictional Force in Circular Motion
That does make some sort of sense on how the frictional force is transmitted from the road to the tire via the stationary contact patch but I still don't understand why is it towards the centre of the circle? -

Undergrad Frictional Force in Circular Motion
Hi Guys, I am trying to understand that how does the frictional force on a car moving in a circle is directed towards the centre? I do understand that kinetic friction acts tangentially to the motion and opposite to the velocity vector but why does static friction act towards...
