What happens to 60% of the work put into the machine and what happens to the other 40%? - I can't quite understand what this problem means and what it is asking for. Is the 60% of the work put into the machine the work input and is the other 40% the work output?

The price for a P-80 machine is in the span of USD 35-45 million of the most advanced display photomasks in the most cost efficient way,” says Magnus north of Stockholm and the Group has subsidiaries in China, France, 

D. 67 kW The efficiency output of a machine is simply the output work divided by the input work, and is usually multiplied by 100 so that it is expressed as a percent. Look back at the pictures of the simple machines and think about which would have the hi Efficiency of a Machinehttps://www.tutorialspoint.com/videotutorials/index.htmLecture By: Mr. Pradeep Kshetrapal, Tutorials Point India Private Limited Maximum efficiency is usually near 75% of rated load. Thus, a 10-horsepower (hp) motor has an acceptable load range of 5 to 10 hp; peak efficiency is at 7.5 hp. A motor ’s efficiency tends to decrease dramatically below about 50% load.

The most efficient electrical machine is the transformer. Transformers have efficiency above 95%.
