  • What is the tension of the rope?

     

    Rope nets are widely used in industry, but what kind of rope net is a good amount? In this case, we must consider the tension of the rope. Let's take a look at the tension of the rope.

     

    It is difficult to explain the tension in detail, but you can understand that a stressed rope can be seen as two ropes connected at a certain point, then the tension at the joint is equal to the tension of the whole rope. Tension is always the tension of the rope. For this reason, the tension theory should also be a vector, but we generally treat it as a scalar.

     

    Pull the force on both ends of the finger. In general, since we believe that the ropes are all "light", the tension at the ends of the rope should be equal. At the same time, the tension inside the rope is also equal everywhere, and its value is equal to the tensile force at both ends.

    By: "The tension at the ends of the rope should be equal." We can know that by looking at the force of the rope connecting the heavy objects, the tension of the whole rope can be obtained.

    Then, in the case of a fixed pulley, there is no change in the rope connecting the heavy objects, and therefore, the magnitude of the force does not change, and the tension of the rope does not change. However, the direction of the tension changes due to the change in angle, and the force is a vector. So you should answer this: the tension of the rope has not changed, the magnitude of the tension has not changed, but the direction of the tension has changed.

    In the case of a moving pulley, the angle of the rope connecting the weight changes, otherwise the object cannot be balanced. Therefore, the magnitude of the tension changes, and the direction and size of the tension change. A qualified rope can be used on the rope net, which is easy to use.
