What is one way to overcome friction in a machine?
use lubricants it smoothens the surface and reduces the irregularity between both the surfaces resulting in reduction of friction
If there was no friction what would that do to mechanical advantage and how would it affect efficiency?
Without friction, some forms of mechanical advantage do not function. In most cases for a mechanical apparatus, a reduction in friction is usually accompanied by an increase in efficiency.
What force stops manchines from being 100 percent efficient?
Reducing its temp. heat is the most common form of energy, and when a machine has friction, it is creating heat. by reducing the amount of friction, maybe by using some kind of lubricant between the objects, it will create less heat and thus use less energy input, with a higher input to out put ratio.
What are the 2kinds of friction?
Static Friction and Kinetic Friction. Static Friction is what friction that slows you down. While Kinetic friction is sliding friction.
What do lubricants do to friction by replacing sliding friction with fluid friction?
Lubricants reduce friction by replacing sliding friction with fluid friction.
Why would you use oil on a smooth surface?
friction reduction
Friction reduction and shock absorption are functions of what part of a long bone?
end
What membrane reduction of friction between the parietal and visceral surfaces?
Serous Membranes
What is one way to overcome friction in a machine?

How would a reduction in friction in a stream channel affect the streams velocity?
As water in the stream channel flows, it encounters friction; the friction slows the forward movement. The shape,size, and roughness affect the amount of friction. High friction slows the stream significantly.
Which supplies enables the reduction of friction on the cable while being pulled?
Wire-pulling lubricant
What has the author G U Wheeler written?
G U. Wheeler has written: 'Friction and its reduction'
Which supplies enables the reduction of friction on the cables while being pulled?
Wire-pulling lubricant
The reduction of friction between the parietal and visceral surfaces of an internal cavity is the function of?
sereous membrane
What are oil products used for?
The reduction of friction in the moving parts of machinery is the primary usage of oil.
Why does friction reduce the efficiency of machines?
Friction requires energy to overcome it. This causes loss of energy in the system. Loss of energy in a system, by definition, is a reduction of efficiency.
If there was no friction what would that do to mechanical advantage and how would it affect efficiency?
Without friction, some forms of mechanical advantage do not function. In most cases for a mechanical apparatus, a reduction in friction is usually accompanied by an increase in efficiency.
