Here , a car turning on a circular track. I have marked all the kinds of friction , velocity happening in the diagram.
For the front wheels ,
VT (Tangential velocity) ,Vr(Radial velocity) , VR(Tangential + radial = Resultant velocity)
fs1 & fs2 is the static friction happening on the front wheels i.e in direction opposite to the direction of velocity since we know friction happens in direction opposite to motion of body.
For back wheels ,
resultant velocity is in front direction & static friction backwards.
Q1 What I think :
Ft=Fs2=0. Therefore , static friction acts in radial direction because static friction at back of wheel = 0 ?
Q2 I think I am wrong because if I find to find total inward force. Then l it will be = centripetal + static friction.
Credits of the picture goes toMr.Kamran. I have just marked the directions.
