What is the mechanical advantage of a machine without friction?
Machinal advantage, also known as mechanical advantage, refers to the ratio of the force produced by a machine to the force applied to it. A machine can be useful even its machinal advantage is less than 1.
Can a machine be use useful with a mechanical advantage of 1?
Yes, a machine with a mechanical advantage of 1 can still be useful by changing the direction of the force applied or by increasing distance moved, even though it doesn't multiply the force. Examples include a pulley or lever.
Can a machine be useful even if its mechanical advantage is less than one explain and give an example?
Yes, a machine can still be useful even if its mechanical advantage is less than one. This can happen when the machine reduces the amount of force needed to perform a task, even though the output force is less than the input force. An example of this is a pulley system, where the force needed to lift an object is reduced by distributing the load over multiple ropes and pulleys.
Why would you want to use a machine with a mechanical advantage less than 1?
Mainly because that's the only kind you can ever get. If you hold out until you find a machine with a mechanical advantage of not less than 1, you'll never get the job done. Or even started.
Is it true a simple machine is one that always gives a mechanical advantage of 2?
Oh, what a lovely question! A simple machine is a device that helps make work easier by either changing the direction or amount of force needed. While some simple machines, like a lever or pulley, can provide a mechanical advantage of 2 or more, not all simple machines will have a fixed mechanical advantage. Each simple machine is unique and can provide different levels of mechanical advantage depending on its design and how it is used. Just like how every brushstroke on a canvas adds to the beauty of a painting, each simple machine plays its own special role in making tasks easier and more efficient.
How do you increase the mechanical advantage of a wedge?
The spokes of a wheel are comparable to levers. Longer spokes give more mechanical advantage. Even in a wheel that is solid, and has no spokes, the greater the diameter, the greater the mechanical advantage.
Can a machine be useful even if it's mechanical advantage is less than one?
aly290 rocks facebook al dae peace out suckers ok who ever rote that better like rething somethings because that answer is just a little wierd and idt any body will know what tht means. the real answer can be given by using examples of machines and by understanding formulas.
How does the different type of pulley system affect the mechanical advantage?
Depending on the type of pulley system you have (Fixed/ movable/ combined pulley) using either of these will give you mechanical advantage. The different pulley types are designed to even the weight of the object your pulled out, this will enable you to lift heavier objects with a lighter pull
Is the pen a simple machine?
No. The classic simple machines are: Lever Wheel and axle Pulley Inclined plane Wedge Screw Using the pen has no mechanical advantage, other than in a ballpoint pen where the roller bearing reduces friction, but is primarily intended to produce an even ink application.
What are advantages of logic circuits?
A: The advantage is that there is no mistakes if the function is proper. The only mistake there can be is the human telling what to do logic is a study of how to make a machine interpret and execute commands flawlessly even though the machine is very dumb itself.
A measure of how much work put into a machine is changed into useful work output?
It's efficiency would be 100%, but it's basically a theoretical ideal, because no matter how much it is minimized, "machine" automatically means a certain amount of friction, and a certain amount of heat generated, even if they are tiny amounts. That prevents 100% efficiency.
Why can't mechanical efficiency be over 100 percent?
The mechanical efficiency can't be over 100% because a type of energy is always lost. For example, it can be lost as heat, sound or even light. When you use a light bulb, it produces light, but heat is lost in the process. See what I mean! In most cases, heat is lost due to friction. the work put out by a machine is always less than the work put into a machine to do the work. Therefore no machine is 100% efficient. As well.... Efficiency is (power out/power in) x 100. To get an efficiency of *more* than 100%, the machine must give more power out than is put in. No machine has ever been demonstrated that does this, and until someone can show this result (power out *more* than power in), we know that any machine has an efficiency less than 100%.
