This video discusses the concept of deformation with respect to different types of loads. It explains how deformation occurs when a force is applied to an object, and how the amount of deformation is affected by the object's stiffness. The video also introduces a new material and explains how it behaves differently under different loads. Finally, the extension and deformation of the two regions are calculated and shown to be the sum of the individual extension values.

**00:00:00**In this video, the concepts of formation and the law of Hooke are discussed. A varilla, for example, is initially formed as a rod with a certain tension, and a certain amount of force is applied to it. This force, called an axial load, causes the rod to undergo deformation. In this example, the rod initially experiences a stretching, which disappears when the initial force is removed. However, if the same force is applied again and the rod is allowed to "recover," a permanent deformation will result. This deformation is illustrated with an experiment called "Attention!" In the early experiments, the deformation was measured by measuring the rod's length before and after the applied force. However, as the applied force increased, the deformation became exaggerated, until it reached a point where it was two hundred times the initial length. At this point, the rod can no longer be considered "normal," and is said to have reached its "maximum deformation." Beyond this point, further increases in force will have little effect on the rod's deformation. The rod will reach a "point of maximum deformability," after which it will start to deform in a linear fashion. Beyond this point, the deformation becomes "nonlinear**00:05:00**In this video, the presenter discusses the concepts of strain and stress and their effects on material behavior. He presents two examples of how these concepts can be used to study material behavior- one involving the application of a stress to a material, and the other involving the application of a strain to a material. He explains that, in both cases, the material will experience a change in its size and shape- the stress will cause it to grow, while the strain will cause it to stretch. He goes on to say that, in order to apply these concepts to real-world situations, it is important to understand the different types of strain and stress that can be applied to materials. He then demonstrates how these concepts can be used to measure the amount of deformation that a material undergoes under various conditions. He concludes the video by discussing the importance of understanding material behavior, and how measurements of deformation can be used to determine the properties of a material.**00:10:00**This video discusses the concept of elasticity and the law of Hooke. Elasticity is a measure of how much an object stretches when subjected to a force. The law of Hooke states that the force applied to a body will cause the body to deform in a linear fashion according to its elasticity. This video provides a simplified example of how elasticity works and explains how the law of Hooke affects the calculation of the stretching of a bar.**00:15:00**The law of Hooke states that force is the same, regardless of the object's shape or suspension system. In this video, Professor Harry Smith explains how this law is used to calculate the stretching or deformation of an object. In general, the force required to stretch or deform an object is determined by its stiffness, or the constant ratio of the object's deformation to its original length. Difficulties arise when dealing with objects made of different materials, which may stretch or deform differently under the same load. In these cases, the equation for stretch or deformation can be used to determine the amount of stretch or deformation in individual molecules.**00:20:00**In this video, the concept of deformation is explained by discussing how it is different based on the loads that it is subjected to. Additionally, a new material is discussed, which results in different loads being applied to it. Another difference between the two regions is that the BC region is in compression while the AV region is in tension. The result of applying the different loads is that the AV region will be stretched in a negative way, while the BC region will be stretched in a positive way. Finally, the extension and deformation of the regions is calculated, and the resulting extension is shown to be the sum of the individual extension values.
