- **Versatile Spring Set**: This product includes five distinct coil springs made from durable steel wire, with tension limits of 5N, 3N, 2N, 1N, and 0.5N. Ideal for various applications requiring different force levels. - **Durable Construction**: Each spring features a nickel-plated finish for enhanced protection against corrosion and wear. The design includes a ring at the top, with a triangular base, a hook, and a pointer at the bottom for secure attachment and easy measurement. - **Proportional Extension**: The red-painted corner of the triangular base indicates the effective working number of the spring. Within its elastic limit, the extension of each spring is directly proportional to the external force applied, ensuring reliable performance. - **Consistent Performance**: Under working load conditions, the non-linear tolerance of spring stiffness at any given point remains within 5% of the average stiffness, providing dependable and consistent functionality across various uses. - **Practical Applications**: - **Educational Use**: Perfect for physics experiments, these springs can help students understand concepts of force, tension, and elasticity. - **DIY Projects**: Excellent for hobbyists and makers who need customizable tension solutions in projects ranging from model building to mechanical designs. - **Industrial Testing**: Useful in quality control processes for testing load capacities in various manufacturing settings. This set combines quality materials, precise functionality, and practical application versatility, making it an essential tool for both educational and professional environments.
