suggest some methods to reduce friction.?

Answer 1

lubrication, reduce the interacting forces (make the load lighter), use wheels, magnets, air cushioning. Thanks all i got.

Answer 2

To reduce friction in cars, lubrication is required. Oiling also reduces friction.

Answer 3

If u want to reduce friction
between solid to solid
1. use lubricunt
2. polish the surface of the oblects.
3. use rolling or ball bearing.
4. use vaccume as in gyroscope.
5. reduce the contact area of the objects

between solid and liquid
1. reduce the viscocity of liqid.
2. use cone shaped objects.

between solid and air
1. use cone shape objects.
2. reduce velocity of the object
3. select the inclination fangle for minimium friction

Answer 4

friction can be reduced by smoothening the 2 surfaces in contact
so that the value of co-efficient of friction is reduced.
Or u can convert the existing friction into rollling friction (which is less than both static and kinetic friction) by placing rollers between the contact surfaces.Rolling friction is negligible.

Answer 5

since friction equals the coefficent of friction times the normal reaction force then by reducing the mass of the object you reduce the friction.

or you could use lubrication to reduce the coefficent of friction

Answer 6

All methods cause pain- the best method is to leave him as nature intended. The uncircumcised penis requires no special care, as the foreskin is fused to the glans until at least age 2. This prevents bacteria and debris from getting in there, and the penis needs only to be wiped like you would wipe a finger. Because the foreskin is fused to the glans, much like a fingernail to your finger, infant circumcision is more painful and more difficult than adult circumcision. The doctor must fisrt make a cut in the foreskin, then scrape it off the glans, and insert a bell device to hold in in place while he slices off the foreskin. The glans then becomes an external organ, and begins to keratanize, or form scar tissue. By the time the child is in adolescence, the glans can be covered in up to 10 layers of tough scarred skin. I have an intact boy. His father is circumcised. I am not worried about the "Why don't I look like Daddy" argument. It's more likely that he will be curious as to why he dosen't look like me. I'm not going to grow a penis to prevent that. He has never had any problems with his natural, unadulterated penis.

Answer 7

METHODS:-
1] apply lubricant to the rubbing surfaces
2] for moving the body which u want to be less frictioned , apply force at an angle 45 degree to the horizontal.
3] make the rubbing surfaces smooth by polish paper and apply polish to it.

Answer 8

which kind of friction? Static or dynamic?
lubrication
if this is a gravity based friction, reduce weight or raise inclien angle

Answer 9

oiling,greasing ,lubricating the surface can reduce friction. you can make the surface inclined (converting into sliding,rolling friction)

Answer 10

from where u want to reduce friction.
u can use oil,greece and anything that reduce friction

Answer 11

we can reduce friction by oiling(lubricating) surfaces,using bearings,or using special materials(ex;teflon:used in "non-stick" frying pans for this reason)
