To calculate the efficiency of a machine, you would need information such as the input work or energy applied to the machine and the output work or energy generated by the machine. Efficiency is typically calculated by dividing the output work or energy by the input work or energy and multiplying by 100 to express it as a percentage.

What would a machine that had 100 percent mechanical efficiency be called?
A machine with 100 percent mechanical efficiency would be called an ideal machine, as it would have no energy losses due to friction, heat, or other inefficiencies.
Does an ideal machine would have an efficiency greater than one?
No, an efficiency greater than one would not be possible, since that would violate a very fundamental law of physics: conservation of energy. The efficiency of an "ideal machine" would be one, in many cases; the efficiency of an ideal Carnot engine would be less than one.
How efficient is a machine that outputs 67J when 150J of work are input?
The efficiency of the machine can be calculated using the formula efficiency = (useful output / total input) * 100%. In this case, the efficiency of the machine would be (67J / 150J) * 100% = 44.7%. This means that the machine is operating at 44.7% efficiency in converting input work to useful output.
What is the efficiency of a machine that requires 100 joules of input energy to do 35 joules of useful work?
The machine efficiency is 35 percent (35/100).
What would be the mechanical efficiency as a percentageof a machine that produced an output of 200J with an input of 250J?
The mechanical efficiency of the machine is calculated by dividing the output work by the input work and multiplying by 100 to express it as a percentage. For this scenario, the mechanical efficiency would be (200J/250J) * 100 = 80%.

Why is efficiency of machine not 100?
If there would be a machine with an efficiency of 100 you would have perpetual motion. Some energy must be lost to friction, heat, gravitational pull.Boss if you have efficiency more than 100 % that means your output is more than input, so from where the excess energy you get ...?
What is the efficiency of a machine that requires 100 joules of input energy to do 35 joules of useful work?
The machine efficiency is 35 percent (35/100).
What would be the mechanical efficiency as a percentageof a machine that produced an output of 200J with an input of 250J?
The mechanical efficiency of the machine is calculated by dividing the output work by the input work and multiplying by 100 to express it as a percentage. For this scenario, the mechanical efficiency would be (200J/250J) * 100 = 80%.
Why would a machine with 100 percent efficiency be considered an ideal machine?
No heat loss = maximum output. There would be no loss of energy, which is an ideal condition.
What type of efficiency would a simple machine have if the output work of the machine equals the input work?
Although it is impossible for any machine to have an efficiency of 100%, it would in this case be 100%. Studies have shown that when ever there is motion, there has to be a loss of energy due to friction. So any rotating machine, big or small will have losses.
You have just designed a machine that uses 1000 joules of work from a motor for every 800 joules of useful work the machine supplies What is the efficiency of your machine?
The efficiency of the machine can be calculated as the ratio of useful work output to total work input, multiplied by 100 to express it as a percentage. In this case, the efficiency would be 80% (800/1000*100).
If the input work on a machine is equal to its out put the machine has what efficiency?
The machine would have 100% efficiency if the input work is equal to its output. This means that all the input energy is fully converted into useful output energy without any loss.
What is the mechanical efficiency of a machine that produces 400 joules or work output from a work input of 500 joules?
The mechanical efficiency can be calculated as the ratio of work output to work input, multiplied by 100%. In this case, the efficiency would be (400/500) * 100% = 80%. So, the mechanical efficiency of the machine is 80%.
Does an ideal machine have an effciency of 100 percent?
No, an ideal machine cannot have an efficiency of 100 percent. This is because some energy is always lost as heat due to factors like friction and resistance. The best an ideal machine can achieve is an efficiency of 100% by having no energy losses.
