Real pulley systems may have friction between the pulley and the rope, causing energy loss and reducing efficiency. Additionally, the pulleys themselves may have mass and size, which could affect the mechanical advantage of the system. In ideal pulley systems, we assume no friction and massless, frictionless pulleys for simplicity in calculations.
What else can I help you with?
What two parts might make a pulley?
A pulley consists of a wheel and an axle. The wheel is the round part that the rope or cable wraps around, while the axle is the rod or spindle that the wheel rotates around. When the wheel and axle work together, they create a simple machine that can be used to lift or move objects.
Why would you use a single fixed pulley to lift a box if the pulley's mechanical advantage is 1?
Because it's more convenient. The pulley in this case is not giving a mechanical advantage, but it is allowing you to locate the motive force somewhere other than directly above the box, which can be significant in that you can, for instance, tie the other end of the rope to a horse or a car on the ground, whereas it might be difficult to persuade either of those things to climb a ladder. Even without that, using a pulley allows you to use your own weight to help lift the box. To lift it from above with a rope, you'd actually have to pull up on the rope. To lift it from below with a pulley and rope, you might just be able to hold onto the rope and relax your legs, letting gravity do some of the work for you.
How does an increase in the load force affect the efficiency of a pulley system?
Increasing the load force in a pulley system can decrease its efficiency due to increased friction and mechanical losses. This leads to a higher amount of energy being required to lift the load, reducing the overall efficiency of the system.
What can a pulley do?
its not to push or pull an object its a simple machine made from a grooved wheel with a rope or cable wrapped around the groove.
Which area of technology might be associated with a computer?
Electromagnetism might be associated with a computer.
What causes a pulley to wobble?
Things that might cause a pulley to wobble: The pulley is bent. The shaft the pulley is on is bent. The pulley is mounted crooked.
Can you bolt a 4.7 Dodge Durango tranny to a 5.2 liter engine?
It might bolt up, but would never shift due to the completely different control systems (computers and electrical plugs).It might bolt up, but would never shift due to the completely different control systems (computers and electrical plugs).
How do you change a pulley on a 92 Pontiac Grand Am?
you will need a pulley puller, pull off the pulley when you replace just bolt it back in place it might take a little muscle to get it started.
What parts might make a pulley?
A wheel, a groove and a rope/chain.
Why might you use a single fixed pulley?
To change the direction of pull.
Squeal from a pully from under the hood when motor is running on a C5 corvette?
if there isn't anything wrong with the belt the pulley is turning, check to see if the pulley is stuck, you might need to replace the pulley ( about $30 )

How do you take a supercharger pulley out?
This all depends on what type of supercharger it is. If you have an Eaton supercharger it is possible that it might be a pressed on pulley. If this is the case then you will need a pulley puller. If the supercharger is a Vortech, Paxton, or ProCharger they all use key ways. So all you need to do is take the bolt off and the pulley might come off. Some times the pulley will not slide off so a pulley puller will work. Or you can heat up the shaft which will cause the pulley to expand and it will then slide right off. DO NOT use a screw driver or any force to pry it off. This can cause damage to the bearings.
Where might one find reviews for fire sprinkler systems?
Reviews for fire sprinkler systems can be found from the Fire Protection Agency and from the Fire Industry Association. These give their own independent reviews of how good the different systems are.
What are the advantages and disadvantages of cast iron pulley?
It is heavy and might damage bearings
How do you remove the pulley on the power steering pump on a Ford Windstar?
You need a special pulley removal tool. And you will also need a special tool to reinstall the pulley. You might be able to buy one at your local parts store.
Is a car a pulley?
a pulley is a wheel with a grooved rim in which a rope, chain, or belt can run in order to change the direction or point of application of a force applied to the rope, etc. There is a pulley in a car the pulley turns the belt that goes around it to turn another pulley that might turn the water pump, or alt., or a/c. Hope this answers your question! :)
