Compression Springs
As you squeeze a compression spring, it pushes back to return to its original length. Rate is the amount of force required for every inch of compression or, for metric springs, millimeter of compression. The higher the rate, the harder it is to compress the spring.
Springs with closed and ground ends sit flat, so they won’t buckle.
