What type of wood do you need for starting a friction fire?
It is best to use a soft wood for the spindle and base board. Some examples of soft wood are cotton wood, elderberry, mulefat, and saguaro. You can also use cattail for the spindle if you are able to find it.

Friction loss is when the water inside the hose rubs against the inner lining and losses velocity as it reaches it destination. So when water is pumped through a hose it losses speed b/c of it rubbing against the inside of the hose. AKA Friction Loss b/c rubbing is another word for friction.
No . You can always start a fire by friction (get two pieces of wood and friction them one against the other. Takes time, but it's spark-free).
The question is not straight forward, and the reason for that is that any material / compound / element that will burn in oxygen, will decay at a particular rate in a fire. So for example, highly combustible materials such as gasoline, or hydrogen, will combust rapidly in a relatively low percentage… of oxygen.. In the case of hydrogen, H 2, the percentage of oxygen required to use up all the H 2 present will be 50%, since the compound produced is H 2 O. If there is this much oxygen present, the result will be quite explosive. For a controlled fire or reaction, you would control the oxygen input, and / or the hydrogen input. Think of an engine in a car, only the fuel in the cylinder gets used / burned, not the entire gas tank! ( Full Answer )
Fuel, Oxygen and a heat source. Fuel, Oxygen and heat are everywhere why is the whole earth not on fire? because it is not Heat but a source of ignition that is needed.
I believe Jinx Wood is the same thing as - or very similar to - Balsawood. It is a very light weight, airy wood that is used by crafters and model builders. It is easy to cut and takes glue very well.
Friction of two pieces of wood causes them to heat up until they reach the combustion temperature end ignite.
heat breaks long cellulose molecules down into shorter molecules that can react with oxygen in a process called 'pyrolysis.' heat is required to initiate pyrolysis in fuel before the fuel will burn. smaller pieces of tinder or kindling will heat more easily than larger pieces. since heat rises, allo…w the flame to rise up the match or tinder to heat additional fuel. Heat can be suppressed with dirt or water, by spreading the fuel apart, or by adding green or wet wood which requires more heat to dry it. ( Full Answer )
All around world people need wood to live. People made farms with wood. Many people use wood for cooking , shelter, and heating. So wood is very useful for us.

Fire is made by the sun, if you want to go camping, and make a fire from wood, get a bunch of wood and you only do this in the daytime before the sun is gone. And pack one or two magnifying glasses. Put the magnifying glass in front of the sun from were you are. And do this when it is very hot outsi…de. Then the sun will shine through, and it will heat up the wood and then you have to wait awhile and then, fire will be on the wood. THATS HOW YOU MAKE FIRE. ( Full Answer )
The best thing to do is buy a box of starter logs. You have to have really hot coals to get many oaks to burn. I use duraflame starter bricks and save half hour of prep time.
we need friction because if there were no friction the objects around us will slide
so you could slow down a car\nor write with a pencil in walking for nailing for braking for slowing down something that is rolling
Friction is the force that resists movement between surfaces that are just touching. If you're walking, it's the friction between your feet and the floor that keeps your foot in place so that you can push off against it and move forward. Without friction, the simplest every day tasks - walking, s…itting down, opening a door - would be impossble - or close to it, just depending on what it is. If we didn't have friction, we'd take an eternity just to screw a lightbulb in - if we ever got the task done at all. Entirely without friction, even the slightest draught would move your furniture across the room. There's actually a video of an experiment that took place in space - the task was to construct something (I want to say jetpack for some reason) in the airless, frictionless space. Two hours later he didn't have the thing anywhere close to finished, and he was sweating, out of breath. He couldn't even move the screwdriver (or whatever he used) without turning with it.

false. Kinetic friction is the friction acting upon a moving object. Itwould be the frictional force against you if you pulled a boxacross a table. Static friction is the frictional force needed to overcome to getan object at rest into motion.
You can actually make a Ouija Board out of anything. Be it a piece of paper, cardboard, or should you be feeling particularly risky, you can draw one on an out-of-sight wall or a large span of concrete. You're welcome to add special symbols or your own added flare, but the only things necessar…y are the letters A-Z and 0-9. Typically writing 'Yes' and 'No' somewhere on there helps too. What you use to pick up the signals can be anything that slides easily along the surface that you choose: a monocle an old broach, a dollar coin... the possibilities are infinite. Have fun - hope this helps! ( Full Answer )
1) Static Friction: When it's hard to move an object (i.e.: moving a large refrigerator box is difficult because of the large mass pressing down and the static friction between the box and the floor) 2) Sliding Friction: Tiny friction particles in between objects that slow them down (i.e.: movi…ng a cafeteria tray in the lunchline--there's a little bit of friction between the tray and the metal bar, which causes the tray to move slowly) 3) Rolling Friction: The friction between wheels (or anything rolling) and the ground. (i.e.: riding a bike. Without rolling friction, we would speed out of control. Walking would also be impossible because our feet collide with the pavement and gently roll off. With no friction, we'd be slipping and sliding everywhere! =D) ( Full Answer )
The trees that grow in Australia (the eucalyptus) famously need a fire to burn their seeds before these will sprout.
You Start a fire in the woods by finding little sticks and rubbing them together when you have a flame find some moss and light it
Cedar Wood is a type of Softwood. Sofwoods are known for its strength, flexibility and versatility.
Start with water sandpaper grain 150 and go reducing to 200, 300 and 400 and finally 600 grain.
I found somewhere online that the coefficient of static friction was 0.36, but I don't remember where so that has little credibility.
Trying to start a fire with damp wood is very difficult. When I backpack I always carry some tinder (dry shavings) to start a fire. Wet wood will not burn unless the fire is hot enough to evaporate the water that is in the wood. You can burn damp wood on an already burning fire but it will not burn …as hot. Wet wood tends to smoke a lot and may go out on a small fire that does not have a good coal base. I have had to use damp wood to start a fire before but I had to shave down the wood until I found dry wood inside. Once you get a small fire started gradually add wood until you can get a hot fire. Too much wet wood at once can put out a fire. Not a good thing when you are cold and wet. Be patient. ( Full Answer )
Well friction is a force that acts between two surfaces in contact. Although it has unwanted effects like loss of energy or wear and tear, yet it is a very important force and is thus sometimes called 'the necessary evil'. At homes friction needs to be increased on stairs, floors, especially bathroo…m floors in order to prevent accidents due slipping or skidding. The greater friction between shoes/feet and the floor, the lesser is the chance of slipping. In bathrooms, water/soap on the floor may reduce friction drastically thus greatly increasing the chances of slipping. ( Full Answer )
u have to get sticks(they r in the place by tur house u have to click on the arrow right above ur house hut thing a cottect them)and then u go back to the fire starting place and click start fire and follow the instructions hoped i help you
There are 2 types of frictions: 1. Rolling friction 2. Static friction 3. Fluid friction
Oxygen is required in order for a fire to continue burning. Without oxygen a flame will extinquish itself.
if you check the owners manual you will find it but if you dont have one then you may get a brief check by looking at the spot where your dorr locks to the car when u close it
A blowup boat that you tie to your real boat too to lay out in the sun, or have some mommy time with a little one that is scared of the water just yet. Under US Coast Guard regulations: Boats under 26 feet, with only outboard motors, with "the construction of such motorboats will not permit the e…ntrapment of explosive or flammable gases or vapors", and with no passengers for hire, does not need ANY fire extinguishers (but why not have one anyway?). kayak ( Full Answer )
Fuel is one of three essential elements needed to start and maintain fire, you also must have oxygen and heat.
No, kinetic friction is the friction an object in motion across a surface experiences. Static friction is the frictional force an object stationary on a surface experiences. in nearly all cases static friction is stronger than kinetic friction. To elaborate, say we place a plate on a table…. Sitting there, it experiences static friction, which resists our efforts to move it. Once we overcome that frictional force, the plate begins to move, but now it experiences kinetic friction, a weaker frictional force. This is why it's harder to get objects moving from a dead stop, but once going it seems easier to make them move faster and faster. ( Full Answer )
Softwoods are coniferous/evergreen trees such as pine, spruce, etc. Deciduous trees are then known as hardwoods If the tree is evergreen.
FFFP foam is alcohol resistant and is effective on a wide variety of Class B materials such as alcohol, polar solvents, hydrocarbons, and combinations such as gasohol. Applying FFFP foam to non-ignited Class B liquid spills will seal the surface minimizing the chance of serious fire. See the rela…ted link for more information. Also refer to NFPA-10 for more specific details. ( Full Answer )
Wood, or any other material, could be used to introduce static friction to a system. The choice of material(s) depends on how much static friction the system requires. Each material has its unique coefficient of friction.
Neither... The wood is the fuel, but first it needs to become a gas. The gas is what burns.
Lignum Vitae is an very dense wood imported from Brazil. It can have a density as high as 1.39 g/cc.
Yes, look at "what is static friction?" Static friction is also known as starting friction.
Class B extinguishers are used for liquid fires such as cooking oils. motor oils, gas and so on. If you don't expect toever have such a fire you probably don't need a class b extinguisher.
According to USCG: For boats under 26ft One B-I type approved hand portable fire extinguisher. (Not required on outboard motorboats less than 26 ft in length if the construction of the motorboat is such that it does not permit the entrapment of explosive or flammable gases or vapors, and if fue…l tanks are not permanently installed. For boats over 26 ft to not more than 40 ft Two B-I type OR one B-II type approved portable fire extinguishers For boats over 40 ft to not more than 65 ft Three B-I type OR one B-I type PLUS one B-II type approved portable fire extinguishers.

It is called "starting friction" and is caused by the uneven surfaces of the desk and of the floor causing the interlocking of the tiny projections in the two surfaces in contact. The view of something which may appear to be smooth looks quite rough when seen by a powerful microscope. The surfaces l…ook more like coarse sandpaper. If you place two sheets of coarse sandpaper face to face you will experience a great deal of frictional force between them. Once the object is moving "moving friction" comes into play and that is always less than the starting friction. ( Full Answer )
sliding friction!It not rolling or fluid friction because they are to easily moved I learned this yesterday 9-18-03
the answer will be meaningless until you specify what kind of wood and how finished.
Yes. That's the main principle behind rubbing two sticks together, and also behind kitchen matches as well, too.
They used Piggy's glasses to fire it by putting in under sunlight and directing it to the wood. Sort of like magnification glass and sunlight.
Agba. It's a large African tree , it's wood is used in furniture making. Ash is another.
YouTube has some great videos available that show several different methods for properly starting a fire in a wood burning fireplace. They even show a method for building an upside down fire.
Three things are needed to make fire: . fuel . oxygen . heat The heat source can be a flame, but it doesn't have to be. Manymodern ovens, stoves and barbecue grills ignite the fuel with anelectrical spark.
There are several that work, but the most well known is flint. Note the "flint" in a lighter is not the rock flint, but a special metal alloy.
Friction is most commonly known as any push or pull. There are fourtypes of friction ; sliding friction, static friction, rollingfriction, and fluid friction. Sliding friction is when something issliding against another surface. Static friction is when there isforce being applied upon a heavy object… or the object is beingmoved on a rough surface. Rolling friction is when something isrolling on a surface and friction slows it down. Finally, fluidfriction is when an object is being slown down on or in water, air,or any others fluid.
