STRINGED COEFFICIEND

Stringed coefficient

Do you know about the coefficient of friction? A frictional force can be calculated from the multiplication of the normal force coefficient geseknya. Friction coefficient is divided into two, namely the coefficient of static friction and the friction coefficient of static friction kinetis.Koefisien used when the object was silent, while the kinetic friction coefficient is used when the body moves. This is where the uniqueness of the coefficient of friction, namely that the coefficient of static friction is always greater than kinetic friction coefficient. For example, if we push the car (from rest), first we need Newton's force of x to push the car so that it can move, but after the car is moving we only need to apply a force of less than x Newton so that it can continue moving car . Can be concluded more difficult than driving a car that still makes cars that are moving to keep moving.
This concept is very unique, especially when we see our lives, a lot of things that have similarities with those principles. The first thing that has the resemblance is when we start something new (things outside of our habits). For example, when we first decided to get up early. For the first time, it's very hard for us to carry out the habit. We need an extra hard effort to execute it. But, after we started to do it continuously and was used, the work we do to get up early was not as heavy as our efforts when we first tried to get up early. From an initially felt heavy, over time become accustomed to and it does not need to do battle again. Another example, when we learn the computer (and all software and other devices), initially seemed puzzling. But after we master it, we even hooked and trying to learn more about computers. What can we conclude from this is, starting is difficult, but if we can get started, then it will be easier.
The second principle is similar to the coefficient of friction is our hard work and efforts to face the problems we face. As spoken by Mr. Yohanes Surya that we should place students (generalization: we all) in a critical position. Here again I want to explain a little about the coefficient of friction, ie, if the force that we give to an object smaller than the static friction, the greater will be the same friction force that we give (sigma F = 0). If we apply a force greater than static friction, then the large size of the force of friction = kinetic friction. Meanwhile, if the style that we give as large as the static friction (this condition is often called a critical condition, where the object will move right, but not moved), a large frictional force will be equal to static friction (in other words the maximum frictional force of a objects). This is the same with our efforts to solve a problem, with which we do business = friction (f), and the situation / problem we face = thrust (F). If we face the problem of a lightweight (less than our maximum ability), then we will also provide a lightweight effort to resolve the problem (and the problem can be solved easily) (F = f). If we are given a problem that is too heavy, then we do business will not be maximum, but lower than the maximum because we feel hopeless and impossible to finish (fk Whereas if we are currently facing a problem that is quite difficult but we can solve (the problem is as much our ability), we will try with all our ability to complete (fs = f max = F). In conclusion, if we face the problem that is easy, we will only spend a little ability, if we face the problem that is too difficult, we will issue a maximum of our capabilities are not, and if we face the problem that is equivalent to our ability, we will issue all abilities us to complete. So, try to solve a problem that is not too easy and not too difficult for us. Try to put ourselves in a critical situation, this can help us achieve the maximum potential that exist in ourselves.
