One of the basic laws of material mechanics and elasticity. It was named after R. Hook in 1678. The content of Hooke's law is: in the linear elastic range of materials, the uniaxial tensile deformation of solids is directly proportional to external forces; It can also be expressed as: under the condition that the stress is lower than the proportional limit, the stress σ in the solid is proportional to the strain ε, that is, σ = ε ε ε, where e is a constant, which is called elastic modulus or Young's modulus. The generalized Hooke's law can be obtained by extending Hooke's law to three-dimensional stress-strain state. Hooke's law laid the foundation for the development of elasticity.

The law of elasticity is one of Hooke's most important discoveries and one of the most important basic laws of mechanics. In modern times, it is still an important basic theory of physics. Hooke's law of elasticity points out that within the elastic limit, the elastic force f of the spring is proportional to the length x of the spring, that is, f= -kx. K is the elastic coefficient of a substance, which is determined by its properties. A negative sign indicates that the spring produces an elastic force opposite to its stretching (or compression) direction. In order to prove this law, Hooke also did a lot of experiments and made various shapes of elastomers with various materials.

This rule began in junior high school. Also known as the law of elasticity, Hooke's law in the plot has nothing to do with it.

As for your question, ...

Prison break is about Hooke's law of mechanics, which is a knowledge point in material mechanics, and it is more complicated to calculate. I remember watching a documentary about blasting methods before. On the solid mass concrete structure, the key stress points are calculated, and then holes are punched in these stress points, and then the minimum amount of explosives required for initiation is put in. The result of detonation is that the influence range of concrete explosion is the smallest. This blasting method is to determine the best blasting effect through accurate calculation, so that other nearby buildings are not affected.

In PB, MS obtains the coordinates of several key stress points of concrete wall by calculation, draws them on the devil's face, and then maps them on the wall by projection. After those stress points are opened, the bearing capacity of the stress points is weakened, and the natural wall is easy to break. MS is a student of civil engineering, so she should be familiar with it.
