Consisting of coiled metal, they are designed to store energy when exposed to a load. Some springs will become shorter when exposed to a load, whereas others will become longer. Regardless, the presence of a load will change the spring&#8217;s length while also forcing the spring to store energy. You can gain insight into how much energy a spring will store by taking note of its spring rate.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The Basics of Spring Rate<\/h2>\n\n\n\n<p>Spring rate is a measurement of how much force is required to change the length of a spring by a given amount. It&#8217;s typically measured in pounds per inch (lb\/in), or in some cases, newtons per millimeter (N\/mm).<\/p>\n\n\n\n<p>Some springs have a spring rate of just 0.67 lbs\/in, whereas others have a spring rate of 2.83 lbs\/in. In the former example, for every 0.67 pounds of force you apply to the spring, you&#8217;ll change its length by 1 inch. If you apply 1.34 pounds of force, for instance, the spring will become longer or shorter by 2 inches.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Compression vs Extension Spring Rate<\/h2>\n\n\n\n<p>Spring rate affects all types of mechanical springs, including compression springs and extension springs. Compression springs are characterized by their ability to become shorter when exposed to a load. As their name suggests, they &#8220;compress&#8221; under a load. Extension springs, on the other hand, are characterized by their ability to become longer or &#8220;extend&#8221; under a load.<\/p>\n\n\n\n<p>For compression springs, spring rate typically represents the amount of force needed to shorten the spring by 1 inch. For extension springs, it typically represents the amount of force needed to elongate the spring by 1 inch.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why Spring Rate Matters<\/h2>\n\n\n\n<p>You should consider the spring rate when choosing a mechanical spring. It provides insight into how stiff or rigid the spring is. Generally speaking, the higher the spring rate, the more stiff it will be. A high spring rate means you&#8217;ll have to apply more force to change the spring&#8217;s length. If it&#8217;s a compression spring, you&#8217;ll have to apply more force to make it shorter. If it&#8217;s an extension spring, you&#8217;ll have to apply more force to make it longer.<\/p>\n\n\n\n<p>Springs must be strong enough to support the load or loads to which they are exposed. If a spring is too weak, it may sustain damage, such as permanent deformation. By choosing a spring with the right spring rate, you can avoid problems such as this.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Mechanical springs are used in a variety of applications.
