Static friction is a self – adjusting force comment.

Self – adjusting force is a force that adjusts its magnitude according to the situation.
Static frictional force is a type of frictional force that tends to keep the body at rest.
When an external force is applied on the body, static friction is generated and it adjusts its magnitude such that it becomes equal to the magnitude of the external force and hence the body remains at rest.
Static friction is thus a self – adjusting force because its magnitude increases or decreases on the basis of the magnitude of external force.

Final answer:
Self – adjusting force is a force that adjusts its magnitude according to the situation.

  1. Explain why (a) The angle of contact of mercury with glass is obtuse, while that of water with glass is acute. (b) Water on a clean glass surface tends to spread out while mercury on the same surface tends to form drops. (Put differently, water wets glass while mercury does not). (c) Surface tension of a liquid is independent of the area of the surface. (d) Water with detergent dissolved in it should have small angles of contact. (e) A drop of liquid under no external forces is always spherical in shape.
