0.5N, 1N, 2N, 3N, 5N J21006 Physics Equipment Physics Experiment Compression Spring Spiral Spring Set Scale Principle of Spring Dynamometer Coil Spring Set
* Five kinds of coil springs made of steel wire are grouped together. The tension limits are 5N, 3N, 2N, IN, 0.5N.
* Nickel-plated protection. The upper end of the spring is a ring, and the lower end is composed of a triangular piece, a hook and a pointer.
* The red paint at the corner of the triangle is the effectivenumber of the spring. Within the elastic limit, the length of the spring extension is proportional to the external force.
* Within thelimit load, the non-linear tolerance of the spring stiffness at each point relative to the average stiffness is not more than 5%.
