According to the stress-strain relationships of elastomers in material mechanics, the stiffness coefficient of a spring depends on several factors. Specifically, it is influenced by N, the shear transverse dimension of the elastomer, R, the radius of the spring wire, and r, the radius of the circular spring. Additionally, n, the number of turns in the spring, plays a significant role. It becomes clear that the deformation of the spring is related to the torsional moment created by the forces at both ends of the spring, rather than being caused by just one of the two forces acting on either side. When one end of the spring is fixed relative to the ground and the other end is stretched to reach an equilibrium state, the spring experiences a pair of balancing forces acting at both ends. These forces generate a moment that counteracts the internal moment resulting from the spring's deformation. The magnitude of these forces can be calculated using Hooke’s Law, with each force being F_k. Therefore, the reading on the spring dynamometer reflects the magnitude of the force applied to one end of the spring. The actual deformation of the spring, however, depends on the moment generated by the pair of balancing forces across the spring. The method of measuring gravitational force using a spring scale illustrates that the scale’s reading corresponds to the weight of the object being measured. In this case, the scale reading is not zero because the object exerts a downward force due to gravity, and the spring responds accordingly. This process highlights the importance of students understanding fundamental physical concepts and laws before conducting experiments. They should grasp the experimental principles and methods, and through collaborative efforts, explore physical laws, which helps develop their teamwork and communication skills. In short, while students must take the lead in the experimental inquiry process, teachers play a crucial guiding role. Teachers should actively monitor the progress of student experiments, provide timely guidance, and ensure that students improve their experimental and investigative abilities through structured support and supervision.
