Will friction in a belt pulley system be reduced when the system is placed in a vacuum?

A vacuum will reduce the air resistance of the rotating pulleys and the movement of the belts. The advantages will however be minimal and hard to measure.
Friction is required for the belts to move and be driven by the pulleys. A vacuum will not affect the contact between the belt and pulley.

Could you use wood for static friction?
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.
Does a pulley system cause the direction of the output force to be opposite to the direction of the input force?
A pulley system may cause the direction of the output force to differ from that of the input force, but is not guaranteed to do so. In a simple example, a double pulley could easily result in input and output forces in parallel.
If 250 watts of power is input into a mechanical system can you get 250 watts of power out?
Yeah all you need is a completely friction less system.
How does a spring pulley system work?
A single sheeve pully has only one wheel a multiple sheeve pully has more than one wheel.
Higher education in china utilizes the key point system which means are placed in key point schools?
Higher education in China utilizes the key-point system which means are placed in key-point schools the smartest students.
What is the mechanical advantage of the pulley system?
The mechanical advantage of the pulley system is the inertia and friction of the unbalanced and balanced forces acting on the mechanical advantage which is part of the pulley system....
How can force be reduced?

What causes the output work of a machine to e less than the input work?
Some of the input force is lost due to friction. If you are using a pulley system then there is friction between the rope and the pulley and there is also friction within the ball bearings of the pulley itself. If you are using an inclined plane there is friction between the plane and the object traveling upon it. In a friction-less world the input is equal to the output.
What is the Role of Conveyor Drum Pulley?
Conveyor pulley manufacturers company use conveyor drum pulley with conveyor system to drive conveyor belt. Tension and friction between pulley and belt decide the quality of conveyor belting system.
1 pulley system more efficient then a 2 pulley system?
Efficiency is the proportion of energy usefully used. Using a pulley system does not use less energy it just changes the ammount of force. Pulleys do have a small ammount of friction so having just one pulley would be more efficient. (but not much more)
How does increasing the number of pulleys affect the ideal mechanical advantage and efficiency of pulley system?
Ideal mechanical advantage is the mechanical advantage when the efficiency of the pullefy system is 100%. It is a constant for that system of pulleys. Therfore it is not affected by increasing or decreasing the load.The MA of a pulley is equal to the number of supporting ropes.If the load is supported by one rope , the M.A of the system is 1. Efficiency is 1 for ideal pulley ( No loss of energy due to friction)If the load is supported by two ropes , the M.A of the system is 2. But Efficiency is still 1 for ideal pulley ( No loss of energy due to friction)If the load is supported by three ropes , the M.A of the system is 3. Efficiency is still 1 for ideal pulley ( No loss of energy due to friction) .And so on.Read more: How_does_increasing_the_load_affect_the_ideal_mechanical_advantages_and_efficiency_of_a_pulley_system
Which is better a incline plane or pulley?
A single pulley simply changes the direction of the force. A block and tackle or multiple pulleys can offer a mechanical advantage - same as an inclined plane. For the same mechanical advantage, a pulley system may be better because of lower friction.
What is double pulley system?
A double pulley system is simple. Instead of one wheel like the single pulley system has, the double pulley system has two wheels and carries more heavier loads than the single pulley system can hold.

How much effort is needed to lift a 75 N weight using the pulley system?
If you are talking about a simple pulley with the pulley attached and load rope attached to the object then you will need a little more than 75N of force. Lifting an object (at a constant velocity) requires a force equal but opposite the weight of the object. With any simple machine you will need to do more work to overcome friction. If you were to use a single pulley with the pulley attached to the object then you will need a little more than 37.5 N. If you were to use a multiple pulley system then you would need to know the mechanical advantage of the pulley system.
