A fire drill, sometimes called fire-stick, is a device to start a fire by friction between a rapidly rotating wooden rod (the spindle or shaft) and a cavity on a stationary wood piece (the hearth or fireboard).
Fluid friction describes the friction between layers of a viscous fluid that are moving relative to each other. [7] [8] Lubricated friction is a case of fluid friction where a lubricant fluid separates two solid surfaces. [9] [10] [11] Skin friction is a component of drag, the force resisting the motion of a fluid across the surface of a body.
The ability to make fire, generally with a friction device with hardwood rubbing against softwood (as in a bow drill), was a later development. [ 13 ] Each of these stages could occur at different intensities, ranging from occasional or " opportunistic " to "habitual" to "obligate" (unable to survive without it).
Fire making, fire lighting or fire craft is the process of artificially starting a fire. It requires completing the fire triangle , usually by heating tinder above its autoignition temperature . Fire is an essential tool for human survival and the use of fire was important in early human cultural history since the Lower Paleolithic .
The original meaning of the word still persists in some pyrotechnics terms, such as black match (a black-powder-impregnated fuse) and Bengal match (a firework akin to sparklers producing a relatively long-burning, colored flame). However, when friction matches became commonplace, the term match came to refer mainly to these.
Fire is the rapid oxidation of a material (the fuel) in the exothermic chemical process of combustion, releasing heat, light, and various reaction products.
A joke referencing the term “fire crotch” has been removed from the digital version of 2024’s “Mean Girls” after Lindsay Lohan publicly took issue with it. “Fire crotch” was ...
Substances with low combustibility may be selected for construction where the fire risk must be reduced, such as apartment buildings, houses, or offices. If combustible resources are used there is greater chance of fire accidents and deaths. Fire resistant substances are preferred for building materials and furnishings.
