High-efficiency machines do more for less and are therefore more desirable than a low-efficiency machine.

Answer

Higher efficiency means lower energy losses and, therefore, such machines are more economical than low-efficiency machines.

Describe why a high-efficiency machine is more desirable than a low-efficiency machine?

Efficiency is the ratio of the energy converted into useful work by the machine to the energy supplied to the machine. Certainly it will not be possible to convert all the energy supplied into useful work because of wastage of energy due to so many reasons. So efficiency will be always less than 1. As the efficiency becomes more the loss would become less. Hence it is desirable.


How does friction effect effiecency?

If there is more friction with a machine, efficiency is less.


What is difference between reversible machine and self locking machine?

Self locking machine has efficiency less than 50% but reversible machines has efficiency more than 50%


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%.


If the efficiency of a machine increases what would occur?

Then the machine would have a greater output power, or alternately, require less input power.

Why is a high efficiency machine is more desirable than a low efficiency machine?

A high efficiency machine will produce more of what is it that you want with the same power as the low efficiency one. In other words, for a low efficiency machine do as much as a high efficiency one, you have to give it more power (energy).

Why does a high-efficiency machine is more desirable than low-efficiency machine?

High efficiency means that a large percentage of the energy used is converted to something useful (the desired output of the machine), and a low percentage is wasted.High efficiency means that a large percentage of the energy used is converted to something useful (the desired output of the machine), and a low percentage is wasted.High efficiency means that a large percentage of the energy used is converted to something useful (the desired output of the machine), and a low percentage is wasted.High efficiency means that a large percentage of the energy used is converted to something useful (the desired output of the machine), and a low percentage is wasted.

Why is efficiency of machine not 100?

If there would be a machine with an efficiency of 100 you would have perpetual motion. Some energy must be lost to friction, heat, gravitational pull.Boss if you have efficiency more than 100 % that means your output is more than input, so from where the excess energy you get ...?

How do you find the efficiency of a simple machine?

The efficiency of a machine is found by considering the useful energy or work that comes out of it, and dividing this by the work that you put into it. Multiply by 100 to get the answer in terms of percentage. You should never get more than 100% efficiency, or 100%, since energy will be lost (to heat caused by friction for example).

Can a machine be more than 100 percent efficient?

100% efficiency would mean that the machine is able to transform energy from one form into another without any loss of energy from the system in the process. For it to have greater than 100% efficiency, it would have to somehow generate additional energy, not contained in the system, in the process, and this is not possible.
