In science, a pulley is a simple machine that consists of a wheel with a groove along its edge to hold a rope or cable. Pulleys are used to lift or move heavy objects by reducing the amount of force needed to do so. They work on the principle of mechanical advantage, making it easier to lift objects by distributing the effort required over multiple ropes and pulleys.

Motor pulley car science project information?
A motor pulley car science project typically involves attaching a small motor to a car chassis, with a pulley system to drive the wheels. By adjusting the size of the pulley, you can explore how different gear ratios affect the speed and torque of the car. This project demonstrates basic principles of mechanical advantage and gear systems in a hands-on way.
What does a fixed pulley mean?
A fixed pulley is a type of pulley that is attached to a stationary object. It changes the direction of the force applied to move an object, but does not provide any mechanical advantage in terms of reducing the amount of force needed to lift the object.
What does the mechanical advantage of a pulley depend on?
The mechanical advantage of a pulley system depends on the number of ropes supporting the moving block or load. More ropes mean a higher mechanical advantage.
What is the velocity ration of a pulley?
The velocity ratio of a pulley system is the ratio of the rotational speed of the driving pulley to the driven pulley. It indicates how the speed of the driven pulley relates to the speed of the driving pulley. The formula is: Velocity Ratio = Diameter of driving pulley / Diameter of driven pulley.
How do you calculate velocity ratio in a pulley?
To calculate the velocity ratio in a pulley system, divide the diameter of the driving pulley by the diameter of the driven pulley. This ratio indicates how much faster or slower the driven pulley rotates compared to the driving pulley. It helps to determine the speed or force transmission in the pulley system.
What does force fixedpulley mean in science?
it mean that the pulley which is a machine that pull stuff has force that fixed the pulley ":"I THINK:""
What is a pulley in science?
It is a wheel that allows for the vector (direction) of a force to be changed. So if I was pulling down on a pulley, the pulley could turn that into me pulling something up.
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 science project will win the science fair?
pulley I vote for a working volcano complete with dinosaurs around it

Where is the pulley in the mercury villager?
It depends which "pulley" you mean. Drive pulleys are on the front of the engine.
Is a wheel along its teeth is its circumference a pulley?

Will the pulley on a power steering pump get loose when it is going bad?
If you mean the pulley and the shaftit is mounted on, Yes! A loose belt on the pulley doesn't necessarily mean anything but a need to adjust the belt tension.
What does it mean when there is a clunking sound coming from whhel that turns belts in the engine?
I'm assuming you mean a pulley, which is what the belts run on. If so, depending on which pulley the bearings could be bad or if it is the crankshaft pulley (big pulley near the bottom) the rubber could be getting bad.
How to unscrew the pulley on a 98 ford windstar?
If you mean the power steering pump pulley, then rent a power steering pump pulley puller tool from Autozone. It does not screw off, the pulley is pressed onto the shaft.
