How can you increase the work output of a machine?
the only way to increase the work output is to increase the amount of work you put into the machine.
Explain why the amount of work that a machine does is less than the amount put into the machine?
Output work is always less than input work.
If machines make work easier explain Why most machines actually increase the amount of work you do in accomplishing a task?
No machine is 100% efficient. The amount of work you get out of the machine is always something less than the amount of work you put into it. So you have to put in more work than the job actually requires. It's the price you pay for making the job 'easier' by using the machine to do it.
How can work be done by an ideal machine?
A robotic machine can be set up to do exacting, repetitive work that would take longer and be more difficult for a human.
Why cant a machine put as much energy out as you put in?
Losses of energy within the machine- some of the energy is used up by friction, and converted to heat. There is also the matter of efficency of a machine. The less efficent, the more power you must put in to get the same output.
What is the ratio of work put out of a machine to the work put in is its?
It is the efficiency of the machine.
How much work put into a machine is changed to useful work put out by the machine?
90%
Is a measure of how much work put into a machine is changed to into useful work by the machine?
Efficiency
How can you increase the work output of a machine?
the only way to increase the work output is to increase the amount of work you put into the machine.
The comparison between output work imput work is?
Work input is how much work you put into a machine and work output is the work done by the machine according to how much work you put into it. You will never get more work out of a machine than you put into it. The efficiency of a machine is how much useful work you got out of the machine compared to how much you put in (expressed in a percent). Efficiency = Useful Work Output ÷ Work Input
How DOS and other operating systems work on same machine?
You can use different OS in the same machine.. Its called the Dual Boot..
How does a vending machine work?
You put money in and BAM. Soda, or snack, or whatever.

How do you calculate efficiency and how is it expressed?
For efficiency, you have to consider the energy or work that you get out of the machine, compared to the energy or work that you put into the machine. Its what you get out, divided by what you put in. By multiplying the result by 100, you should then get the efficiency expressed as a percentage, which is the normal way of describe how efficient a machine or process is. efficiency = (Work out/Work in) x 100 Sometimes you are given the efficiency in a problem, but then have to calculate either the work out or work in, so then its just a case of rearranging the equation above.
