I found a satisfying answer on http://www99.epinions.com/content_131343748740.
I copied it, but it comes from them
The tertiary amines (ammonium salts), Sefose (fatty acids, iodine and peroxide), Methyl Esters (bromo carboxific acids) fatty acids, glycerine and alcohols are blended with just the right proportions to create a cleaning solution that doesn't require much moisture, but holds together long enough to produce thorough and complete cleaning AND slowly disintegrates without leaving a mess.
Unfortunately, the mixture of these chemicals makes the eraser not fit for every kind of surface. It can actually scratch or remove the paint on certain kinds of finishes.
So, with all these chemicals, is it safe to use?
Absolutely! The combination of these chemicals not only creates a very effective cleaning product but at the same time, breaks down the harmful chemicals normally found in cleansers. HOWEVER, please keep in mind that some people do have extremely sensitive skin and any kind of chemical, no matter how slight or diluted can cause irritation. Should that happen, rinse thoroughly with cool water. Remember that no matter how mild these chemicals are, they will sting should you get them in your eyes. Don't rub your eyes until you've washed off your hands. Should you forget, just rinse your eyes with cool water until the stinging stops.
EXTREME CAUTION
Please remember that this eraser contains a chemical that breaks down to AMMONIUM SALTS………… DO NOT MIX WITH CHLORINE BLEACH! Ammonia and chlorine are not meant to be combined.
A microweld is an area where the microscopic bumps on two surfaces stick together. Microwelds are the source of friction.
it is the drive where the driver pulley is compressed by belt on slack side and with less friction on the driven pulley with opposite direction of motion.
A synonym for friction would rub. :DA synonym for friction would rub. :D
Rubbing two sticks together causes friction and the friction may spark a fire. I knew my parents were arguing because I could feel friction in the room as soon as I entered it.
friction
FRICTION-The rubbing of one object or surface against another.
Friction force hasn't a chemical formula.
in chemical pathology department,causes of friction with regard to staffs could be as a result of lack of definition of duty, disparity in income,and headship of the department as witness in my country Nigeria.Also lack of respect for each other's profession is also a cause of friction.
The definition of sliding friction is the force that prevents a sliding object from moving.
static friction,limiting frictionand kinetic friction
Fluid Friction is friction created by a fluid or gass, and sliding friction practical says it in the name stupid
it is when friction occurs when moving parts have ball bearings.
By definition, friction is opposite of the direction of motion.
Friction is a force that opposes the motion of any object moving on it.
The scientific principle is friction.... and heat and ultimately the FIRE
Look for a Book Fool. >.<
You could classify it as kinetic dry friction.
