Explain Why Machines Are Not 100 Percent Efficient

It is so obvious that our huge factory machines are made of simple machines in parts. Solution for Explain why machines are never 100 efficient.

Nisha4281 nisha4281 14022020 Physics Secondary School answered Explain why machines are never 100 percent effecient.

. Is the percent of input work that becomes output work. This is why simple machines arent 100 efficient compared to the world of haste we live in. Inclined Plane- is a.

Most machines transfer energy from one place or another or transform one form of energy eg. It is a measure of how well a machine reduces friction. Machines are not 100 efficient because some of the work done by a machine is used to overcome friction.

So work output is always less than work input. Start your trial now. The only proof I have is showing the Carnot cycle is the most efficient and that is only 100 efficient if the cold reservoir is at absolute zero which it can not be at.

Why can a machine not be 100 efficient. Friction wind resistance and even gravitational pull can all reduce the 100 machine efficiency. A machine cannot be 100 percent efficient because output of a machine is always less than input.

A machine is not 100 efficient because 1a part outs work done on machines is wasted in overcoming the friction between the various parts of machine. 2Its moving parts are not weightless. Answer 1 of 22.

Using the equation learned and with the aid of the calculator solve for the unknown quantity. A machine cannot be 100 percent efficient because output of a machine is always less than input. Some are very efficient.

3The string in it if any is not perfectly elastic. First week only 499. On the surface this sounds like absolute effeciency so is a supercunductor considered not to be.

Chemical into another eg. Supply the table with the final answer obtained from the computation to show the. All we do is that complex that simple machines to work faster and in a improved version.

Thats because all machines must use some of the work put into them to overcome friction. A certain amount of work done on a machine is lost to overcome friction and to lift some moving parts of the machine. A machine cannot be 100 percent efficient because of energy lost to friction.

Why is it impossible for a machine to be 100 percent efficient. Mechanical but machines cant create any form of energy. The learners should be able to verify that machines are not 100 efficient.

Get the answers you need now. I have never explicitly seen why the fact that entropy must always increase or stay the same results in the prevention of achieving 100 efficiency. Click to see full answer.

Get the answers you need now. Done by machines is calculates as Mechanical Efficiency which is Work Output divided by Work Input. Add your answer and earn points.

Kaypeeoh72z and 108 more users found this answer helpful. Correct answer to the question Explain why machines are never 100 efficient. Study the table below.

4Its different parts are not perfectly rigid and also not perfectly smooth. Explain why machines are not 100 efficient. Out of curiosity I realise that a 100 effecient machine is said to be impossible but how is this principle prooved out in the case of superconductors.

A certain amount of work done on a machine is lost to overcome friction and to lift some moving parts of the machine. 1 See answer nisha4281 is waiting for your help. Explain why machines are never 100 efficient.

This tendency of systems to lose energy is called entropy. Systems always tend toward a state of decreasing order unless more energy. Is the number of times a machine multiplies the input force.

Explain why machines are never 100 percent effecient. Weve got the study and writing resources you need for your assignments. Think of the car enginelinear motion with pistons sealing against the piston bores major friction.

Then convert to rotary motion via crankshaft mounted in sleeve bearingsmore friction. A superconducting wire is a machine that transports an ellectric current from one place to another without any loss. For the huge work that we need in our world cannot mach to simple machines.

Entropy in a closed system never goes down. Mostly its friction for the majority. A set of bicycle gears or a hydraulic engine can convert 9599 of the input energy to work.

No machine can convert all their fuel or input energy into work. But some is always lost in other forms of energy such.
