Inventors have not been able to create a machine that is 100% efficient due to the fundamental laws of thermodynamics, particularly the second law, which states that energy transformations are never perfectly efficient and always result in some energy being lost as waste heat. Additionally, factors such as friction, material imperfections, and environmental influences contribute to energy losses. These inherent limitations in physical systems make it impossible to achieve absolute efficiency in any machine.

What is a device in which work output equals work input?

A perfectly efficient machine, which doesn't exist in the natural world. The reason it doesn't exist is because any kind of work gives off energy byproducts (for instance, heat differential, friction, so on and so forth). Kind of like a perpetual motion device (which you could make by linking the outputs to the inputs on a perfectly efficient machine).ideal machine

Why women are not able to do inventions like men?

that is a total lie, the only reason there are more male inventions is because in the past women were not allowd to invent things, and so men created most past inventions that is a total lie, the only reason there are more male inventions is because in the past women were not allowd to invent things, and so men created most past inventions


Can you put Drano in the washing machine tub and spin out so it goes into the drain pipes?

No reason why not - simply run the machine 'empty' (with no washing in) - and follow the instructions on the packaging. It's a good idea - especially if you're in a 'hard water' area. Performing periodic cleaning of an empty machine will prolong its life.


How you can improve the efficiency of lathe machine?

In order to increace the efficincy of a machine, you must eliminate losses of energy between the input and the output. This almost always means reducing or eliminating friction, either within the guts of the machine, or between the machine's moving parts and the outside world. That's the reason that greases, oil, other lubricants, and streamlining are so popular.

Why did James puckle invent the machine gun?

For the same reason that most inventors create things- to make money from the sale of the thing. The Puckle Gun wasn't actually a machine gun, though.


What role does friction have in reducing mechanical efficiency?

Friction is the reason that you can never have a 100% efficient machine. It is the reason that most machine have horrible efficiency.


Did Michael Jackson invent the sidewalk?

No Michael Jackson did not invent the sidewalk -Arthur Wesley Hall and William Alexander McVay created concrete partitions in New Brunswick in 1924. Michael Jackson did However create the Moonwalk!

What was the reason for the delay in the making of the telegraph?

The delay in the making of the telegraph was primarily due to the technological challenges and the need for advancements in electrical engineering. Early inventors faced difficulties in developing efficient and reliable methods to transmit signals over long distances. Additionally, there were financial constraints and competition among inventors, which slowed progress. It wasn't until Samuel Morse developed a practical system in the 1830s that the telegraph became a viable communication tool.

What can you do if you invent a revolutionary machine and your employer terminates you without reason because of the machine's capability of mass production?

A really intelligent company would want to "keep" you and help you to get a Patent for your wonderful invention? You did get a U.S. patent for it, right??? == == Patent the machine first. Although, many many US companies have a contract that anything you invent while working for them, belongs to them for a nominal fee. I once interviewed the man who invented the original pop-top can. He was working in sales for US Can Co. at the time (not research and development.) They paid him $1 for the invention and it was upheld in court.
