You are going to have to make a bunch of assumptions and simplifications. If you look at a real rope hanging over the edge of a real table you will see that , due to the fact that the rope has some stiffness, it does not make contact with the tabletop near the edge (or at least the contact pressure is less there) and the contact pressure at the edge can be rather high.
I will not go through the calculations (I've forgotten a lot of my "Statics" unfortunately).
To determine the coefficient of static friction, you can conduct an experiment by gradually increasing the angle of an inclined plane until an object on the plane just begins to move. You can measure the angle at which this occurs and use it to calculate the coefficient of static friction using the formula: coefficient of static friction = tan(angle).
Limiting friction in Hindi is called "सीमित संघनन". It represents the maximum amount of friction that can be generated between two surfaces before one begins to slide over the other.
I'd like to make this sound interesting, but the answer is that nothing happens. In the absence of forces that might move the object, it will just sit there. Static friction refers to friction between two objects that are not in relative motion. If your frictionless surface is a board and you tilt it, gravity will immediately cause the object to slide. If i put your object on my sandpaper-covered board, I'd probably almost have to tip it over to get the object to move.
Kinetic friction is commonly thought of as the friction between two objects while those two objects slide against each other. To determine the coefficient of kinetic friction (for an object under the influence of gravity on some surface), one needs to determine the angle at which the sliding object moves at a constant speed down the other object (think of a flat piece of rubber sliding down a flat plank of wood). This is different from static friction where the sliding object has some applied force to move along a surface, but that object is stationary because of the friction applied by the surface. To determine the coefficient of static friction, one needs to determine the angle at which the sliding object begins to move down the surface.
The force that begins with an "f" is Friction. It is a resistive force that opposes the motion or attempted motion of an object past another with which it is in contact.
The slope of the static friction vs normal force represents the coefficient of static friction. This coefficient indicates the maximum frictional force that can be exerted between two surfaces before one begins to slide over the other.

Place the object on the plane. Slowly increase the angle of the plane until the object begins to move at angle Θ. The µs = tan Θ. For µk, same process, but give the object a little push at each increasing value of Θ.
The angle at which a copper block begins to slide depends on the coefficient of friction between the block and the surface it rests on. When the angle of incline exceeds the angle of static friction, which can be calculated using the formula ( \theta = \tan^{-1}(\mu_s) ) (where ( \mu_s ) is the static friction coefficient), the block will start to slide. Therefore, knowing the specific coefficient of friction for copper against the surface is essential to determine the exact angle.
It's not. The coefficient of static friction is only equal to the tangent of the angle of incline at the maximum angle before the object begins to slide. At this point static friction equals the component of the weight along the incline (weight X sin alpha). Static friction is given by the coefficient of static friction times the normal force (weight X cos alpha) fs = us N = us mg cos(alpha) Wx =mg sin(alpha) fs = Wx us mg cos(alpha) = mg sin(alpha) us = [sin(alpha)] / [cos(alpha)] = tan(alpha) Similarly, the coefficient of kinetic friction equals the tangent of the angle of incline only if the object is sliding down the incline at constant velocity (net force equals zero). If the object is accelerating along the incline (make this the x axis): Fnet, x = Wx - f max = mg sin(alpha) - uk mg cos(alpha) uk = [g sin(alpha) - ax] / [g cos(alpha)]

Friction and air resistance. All of its kinetic energy gets converted to heat.

The maximum friction that can be generated between two static surfaces in contact with each other. Once a force applied to the two surfaces exceeds the limiting friction, motion will occur. For two dry surfaces, the limiting friction is a product of the normal reaction force and the coefficient of limiting friction.
When you move a heavy object, you must apply a lot of force before the heavy object begins to move. This resistance you feel while the box is NOT moving is static friction. Static friction opposes movement in an initially non-moving object.

The angle of uniform slip refers to the maximum angle at which an object can be tilted or inclined before it begins to slide or slip on a surface. This angle is determined by the coefficient of friction between the object and the surface, and it represents the balance between gravitational force acting on the object and the frictional force resisting the slip. When the angle exceeds this threshold, the static friction is overcome, leading to motion. Understanding this concept is crucial in fields such as engineering and physics, particularly in analyzing stability and motion.
