As with hemp oil, delicate nut oils like hazelnut should be stored in the refrigerator once opened to preserve freshness. Buy only the amount youâll use within three to six months for peak flavor. Best uses: Skip the frying pan and use hazelnut oil to gussy-up cooked rice, quinoa, or oatmeal.
Hinge is a joint. It is designed to join two 'arms' together while letting them move freely. A lever is when a pivot, load, effort is present. Although hinge itself is not a lever, but taking our biceps as an example, that would be a Class 3 lever.
A lever can be used to reduce force to move a load a particular distance or to move a load a larger distance for the particular force. This can be measured in several ways, all of which are ultimately a function of the ratio of lever arm segment lengths (the equatios for this depend on the type of lever you're using).
