They indicate the force required to move two surfaces parallel to each other that are loaded with a weight. The lower the coefficient of friction, the easier the movement. The coefficients of friction are influenced by many factors. These include the materials of the surfaces, their roughness, the presence of lubricants, the ambient temperature and the humidity.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cstrong\u003eHow is the coefficient of friction calculated?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe formulas for calculating the static and dynamic coefficient of friction are as follows:\u003c\/p\u003e\n\u003cp\u003eCoefficient of static friction: μ\u003csub\u003es\u003c\/sub\u003e\u003cspan\u003e \u003c\/span\u003e= A\u003csub\u003es\u003c\/sub\u003e\/B\u003cbr\u003eCoefficient of dynamic friction: μ\u003csub\u003ek\u003c\/sub\u003e\u003cspan\u003e \u003c\/span\u003e= A\u003csub\u003ek\u003c\/sub\u003e\/B\u003cbr\u003e\u003c\/p\u003e","brand":"ZwickRoell","offers":[{"title":"Default Title","offer_id":50928031793319,"sku":null,"price":4100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0741\/2688\/5031\/files\/ZR_1595_20MB_or_less.png?v=1782908749","url":"https:\/\/shop.zwickroell.com\/en-us\/products\/package-for-coefficient-of-friction-testing-of-plastic-films-na","provider":"ZwickRoell","version":"1.0","type":"link"}
