Can you describe( graphically,like a diagram,or a picture) how a friction force plays the role of the centripetal force?For example, a car performing an uniform circular motion on a plane in a idela situation.The car will perform the turn because of friction forces between tyres and surface.But I can't visualize it so clearly as a situation which consists of a wire attached to a rigid body which makes it spin around an axis,assuming the tension exerted on the cable the role of centripetal force.In the case of friction on steering tyres,I accept friction force having the same direction as the centripetal force because the radial acceleration has the same direction and sense as the latter(as m numeric value in F=ma is always positive ).So,can you help me would a free body diagram would be drawn?
