A lubricant (sometimes shortened to lube) is a substance that helps to reduce friction between surfaces in mutual contact, which ultimately reduces the heat generated when the surfaces move. It may also have the function of transmitting forces, transporting foreign particles, or heating or cooling the surfaces.
Dry lubricants or solid lubricants are materials that, despite being in the solid phase, are able to reduce friction between two surfaces sliding against each other without the need for a liquid oil medium. [1] The two main dry lubricants are graphite and molybdenum disulfide. They offer lubrication at temperatures higher than liquid and oil ...
Lubrication mechanisms such as fluid-lubricated systems are designed so that the applied load is partially or completely carried by hydrodynamic or hydrostatic pressure, which reduces solid body interactions (and consequently friction and wear). Depending on the degree of surface separation, different lubrication regimes can be distinguished.
Here a key goal of lubrication theory is to determine the pressure distribution in the fluid volume, and hence the forces on the bearing components. The working fluid in this case is often termed a lubricant. Free film lubrication theory is concerned with the case in which one of the surfaces containing the fluid is a free surface. In that case ...
Many people having sex (including solo sex) know that lube is a must-have in their pleasure tool kit. Lube can make sex less likely to cause uncomfortable friction, which can result in pain or injury.
Self-lubrication is ideal in situations where normal lubrication is difficult, troublesome, or impossible. For example, in paper and food processing, lubrication is undesirable due to product contamination. (Chain companies like Tsubaki and Renold PLC also offer sintered bushes impregnated with food grade lubricant.)
The best way to avoid pesticides, if that’s a health concern, is to go with organic food, as unlike organic foods, conventional, non-GMO foods are still likely exposed to pesticides.
Foods high in protein can help you feel fuller, and some research suggests they may even help reduce cravings. Beyond your main meals, make sure to have healthy snacks on hand, like dried fruit ...
