sir, the rolling friction laws are 1. the rolling frictional force is inversely proportional to radius 2. it increases with area of contact. FOR A BIGGER WHEEL RADIUS IS GREATER.THE AREA OF CONTACT IS GREATER.SO FRICTION IS GREATER. BUT FROM FIRST POINT THE FRICTION SHOULD BE LESS IF THE WHEEL RADIUS IS GREATER. HOW THIS IS POSSIBLE PLEASE EXPLAIN

Dear Srinivas,

Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction:

  • Dry friction resists relative lateral motion of two solid surfaces in contact. Dry friction is subdivided into static friction("stiction") between non-moving surfaces, and kinetic friction between moving surfaces.
  • Fluid friction describes the friction between layers within a viscous fluid that are moving relative to each other.[1][2]
  • Lubricated friction is a case of fluid friction where a fluid separates two solid surfaces.[3][4][5]
  • Skin friction is a component of drag, the force resisting the motion of a solid body through a fluid.
  • Internal friction is the force resisting motion between the elements making up a solid material while it undergoesdeformation.

For a given load if the radius is increased ,the bump produced by the curvature is less and rolling friction is reduced
