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.
A pulley system is used to lift a 2000 newton engine up a distance of 3 meters How much force will the operator have to apply if the mechanical advantage of the pulley system is 4?
A pulley system is used to lift a 2,000 newton engine up a distance of 3 meters. How much force will the operator have to apply if the mechanical advantage of the pulley system is 4? mechanical advantage = 500 newtons.
What is an example of a fixed pulley?
An example of a fixed pulley would be a well. This is a fixed pulley because the pulley doesn't move even though it is attached to an object.
What is a fixed pulley?
A fixed pulley is a pulley that is attached to a support. It does not reduce the effort needed to lift the load, but rather changes the direction of the applied force.An example of a fixed pulley would be the rope pulley on a well. This is a fixed pulley because the pulley doesn't move (it is attached to the overhead structure).
If pulley a turn clockwise at 15 rpm how fast and what direction will pulley b turn?
A simple enough question, but complicated by so many possible variations. For instance, place two cog wheels together so that their teeth mesh. Turn cog A clockwise and cog B will turn anticlockwise (counterclockwise in America). But if you replaced the toothed cogs with a pair of single pulley wheels with some distance apart. Pulling on the rope would turn the top pulley A clockwise and the pulley wheel B clockwise also. But, let us suppose that the rope has been deliberately twisted (not straightly laid) then the pulley B would be turning anticlockwise when the pullet A was turning clockwise.The rate of travel (RPM) would depends on the diametres of the pulley wheels - variations once more!
What is the mechanical advantage of single fixed single movable pulley system?
The mechanical advantage would be 1 because the force required to life the mass of an object becomes 1/2 the original weight of the object.

How would you describe the function of the reproducive system?

What type of pulley would increase the output force?
A pulley system that has multiple pulleys in line with each one having its output drive the next will increase the force. This would be called a tackle pulley.
What adjectives would describe a single celled protozoan?
what adjectives describe a single celled protozoan?
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)
Why would someone want to use a single pulley?
Although a single pulley doesn't offer a mechanical advantage as does the compound pulley, sometimes it can be helpful to change the angle. For example, when lifting an object, it may not be desirable or possible to stand directly above or below it. A single pulley allows one to stand to the side and pull. It also eliminates the friction associated with pulling a rope over a sharp edge, which would be the case if pulling at an angle over the edge of, say, a rooftop.
How conveyor belt head pulley works?
A Conveyor belt's head pulley is also known as the drive pulley, its on this end of a conveyor system where the motorized pulley is installed. At this point the conveyed material is discharged "wherever" and the belt wraps around and begins its return cycle. The head pulley is at the discharge so that the conveyed material is "pulled" through the system vs. having the tail pulley motorized which would be forcing the system to "push" the belt containing the conveyed material.
What are some advantages of using gears and a chain system on a bicycle instead of a pulley system?
Chains mesh with sprockets without slipping. A pulley system would need to use higher tension(and suffer higher losses) to avoid slipping.
What is the American Indian's personality?
I am no expert of American Indians, but I doubt there is a single "personality" that would describe such a diverse cultural community. To try and describe a single personality would be relying on outdated and offensive stereotypes.
How much effort force would you use to lift a kg weight with a fixed pulley system?
a lot
How would you best describe a dictatorship?
