Scientific Enlightenment:

Hooke's Law, formerly translated as Hooke's Law, is a fundamental law of elasticity theory in mechanics, which states that in solid materials, the stress in the material is linearly related to the strain (the amount of deformation per unit). Materials that comply with Hooke's Law are known as linear elastic or Hookean materials.

Science Project:

1. Prepare the necessary materials for the experiment.
2, As shown in the diagram, assemble it.
3, After the installation is completed, perform the debugging.

Scientific Principles:

From a physical perspective, Hooke's Law stems from the fact that the atoms within most solids (or isolated molecules) are in a stable equilibrium state without external loads.
Many practical materials, such as a prismatic rod with a length L and cross-sectional area A, can be modeled in mechanics using Hooke's law—its unit strain (or contraction) is directly proportional to the applied stress (σ) under a constant coefficient of elasticity (E), which is known as the elastic modulus. This relationship is expressed as: F = -kx or ΔF = -kΔx, where F is the force exerted and x is the displacement.
Among them is the total elongation (or contraction). The Hooke's Law is named after the 17th-century British physicist Robert Hooke. The process of Hooke proposing the law is quite interesting. He published a Latin riddle in 1676 and revealed the answer two years later, which was the central content of Hooke's Law.

Experimental Cognition

Hooke's Law states that within the linear elastic range of materials, the uniaxial stretch deformation of a solid body is directly proportional to the applied force.
It can also be expressed as: under the condition of stress below the proportional limit, the stress σ in the solid is proportional to the strain ε, that is σ=Εε, where E is a constant, known as the elastic modulus or Young's modulus. The Hooke's law is extended to apply to

Three-dimensional stress and strain states can lead to the generalized Hooke's law. Hooke's law laid the foundation for the development of elastic mechanics. The generalized Hooke's law for isotropic materials has two commonly used mathematical forms.

  Before assembling, please check if the circuit is unblocked and all the components are complete. Ensure that all contact points are in good contact. During the assembly process, be careful not to get glue on your clothes or skin. Keep the parts out of reach of younger siblings to prevent them from swallowing them by mistake! Do not play with them on your head, to avoid the model falling and injuring you!
