What is the diagram of static friction and how does it illustrate the relationship between the applied force and the maximum frictional force that can be exerted on an object at rest?

The diagram of static friction shows the relationship between the applied force and the maximum frictional force that can be exerted on an object at rest. It illustrates that the maximum static frictional force is directly proportional to the normal force acting on the object, and it opposes the applied force until the object starts moving.
