What is a sentences using compound machine?
Here is a compound machine.
What is the efficiency of a simple machine?
Efficiency % = (work out / work in) * 100 (Work = force * distance)
Why a normal machine could not have the mechanical efficiency of 100?
Because there is always going to be friction, the efficiency of any machine will always be less then 100 percent.
What is mechanical efficiency in science?
mechanical efficiency is the percent of the energy that you put into a machine that was transferred to the load.
Is a tv a compound machine?
A compound machine is any type of machine that is made from two or more simple machines working together. A modern TV is not a compound machine since it has no moving parts.
How is the efficiency of a compound machine calculated?
The efficiency of a machine is found by dividing the amount of work done by a machine by the amount of energy used by a machine. The answer is then multiplied by 100 to give a percentage.
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).
Is a measure of how much work put into a machine is changed to into useful work by the machine?
Efficiency
A simple machine requires this in order to operate?
The mechanical advantage of a compound machine is the multiple of the separate mechanical advantages of each simple machine. The efficiency of the compound machine is also the multiple of the separate efficiencies of each simple machine. So the work in to the first machine multiplied by all of the simple machine efficiencies gives you the work out of the last machine
Why is the mechanical efficiency of most compound machines lower than most simple machines?
It is lower because compound machines have more moving parts that a simple machine does.
Describe why a high-efficiency machine is more desirable thana 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).
Mechanical advantage of a compound machine?
MA = Revolutions of input shaft / Revolutions of output shaft. (Input torque * MA) * efficiency = Output torque Note 100% efficiency = 1.0
The efficiency of a machine is usually expressed in?
The efficiency of a machine is usually expressed as a percentage. The ideal efficiency of a machine is 100-percent.Another AnswerThere are no units of measurement for efficiency, because you are comparing like with like: output power divided by input power.
Why it is important for you to reduce friction on compound machine?
Because too much friction can damage the simple machines that make up the compound machine.
What is a computer a simple machine or a compound machine?
its a compound machine
Can you give me example of a compound machine ASAP?
a compound machine is a machine that is compound and an EXAMPLE OF A COMPOUND MACHINE IS THAT IT IS LIKE A CAR BECAUSE A CAR IS COMPOUND! GOT IT GET IT GOOD!
A measure of how much work put into a machine is changed into useful work output?
It's efficiency would be 100%, but it's basically a theoretical ideal, because no matter how much it is minimized, "machine" automatically means a certain amount of friction, and a certain amount of heat generated, even if they are tiny amounts. That prevents 100% efficiency.
