How do pulleys make work better?
Well, since a pulley is a SIMPLE machine it makes work better because all you have to do is put effort to a pulley instead of using your hands
Give the ways of increasing and reducing friction?
By making the surface rough for increasing friction....... use any lubricating material to reduce the friction.. use rollers to decrease the friction force.. make less contact between 2 connecting materials..
What is the simple machine a pulley?
A pulley is a simple machine that consists of a wheel with a groove and a rope or cable that runs through the groove. It is used to change the direction or magnitude of the force applied to lift or move objects. By reducing the amount of force needed to move the object, pulleys make it easier to perform tasks.
Explain how air friction is reduced in cars and bicycle?
The front of the car is blunt, making it easier to 'cut' through air, thus reducing friction. For a bicycle, since it is very thin and angular, its shape (and the tires') makes it easier for air to glide over the bicycle, thus reducing friction.
Why increase friction?
You would increase friction so that you wouldn't slip, by using the brakes on your car of bike you increase friction to stop yourself. Hikers increase friction between their feet and the ground by wearing hiking shoes that grip the ground better. Tires on cars that create more friction make the car go faster, because instead of sliding, the tires grip the ground and push off.
What can make machines more efficient by reducing friction?
the relationship between them is that the machines have friction that makes the machine goes
What role do ball bearings play in a fishing reel?
Bearing make the reel preform smoother by reducing friction.

What does double pulley system mean in science?
A "double pulley" may refer to a two-block (two rope) pulley, or to the arrangement of two separate pulley blocks as a "block and tackle" -- designed to make lifting easier by reducing the necessary lifting force: a smaller force is applied over a greater distance to achieve a mechanical advantage.
What is the definition of lubricate?
To make smooth or slippery; as, mucilaginous and saponaceous remedies lubricate the parts to which they are applied., To apply a lubricant to, as oil or tallow.
What is maglev?
"magnetic" "levitation" A cute way to make trains float - thus reducing rolling friction, but NOT air friction.
Can friction make object yes or no?
Friction can make object no.
Will faulty alternator cause serpentine belt to melt on pulley in a 1992 cutlass ciera station wagon?
If I am understanding correctly, it sounds like a pulley may be bound up. Thereby causing the belt to rub and make alot of friction thus causing melting. It could be any pulley in the serpentine system. Remove the belt and feel all pulleys for any play.
Did Archimedes make the pulley?
no
How does a movable pulley make work easier?
A fixed pulley is the only pulley that when used individually, uses more effort than the load to lift the load from the ground. The fixed pulley when attached to an unmovable object e.g. a ceiling or wall, acts as a first class lever with the fulcrum being located at the axis but with a minor change, the bar becomes a rope. The advantage of the fixed pulley is that you do not have to pull or push the pulley up and down. The disadvantage is that you have to apply more effort than the load
Why does oil make a bicycle work better?
Oil can reduce friction between moving parts, and protect exposed metals from rust.
