The efficiency of a machine is typically calculated as the ratio of useful work output divided by total work input, then multiplied by 100 to get a percentage. For example, if a machine outputs 80 units of useful work for every 100 units put in, the efficiency would be 80%.

What ratio of output work to input work expressed as a percent is the of a machine.?

The efficiency of a machine is a measure of the ratio of output work to input work, expressed as a percentage. It is calculated as: Efficiency = (Output Work / Input Work) x 100% A more efficient machine will have a higher percentage, indicating that a greater percentage of input work is being converted to useful output work.


Is the efficiency of a machine is 60 the percentage of work input used to overcome friction?

No, efficiency of a machine is a measure of how well input energy is converted into useful output work, and is calculated as useful work output divided by total work input. The percentage of work input used to overcome friction would be related to the frictional losses in the machine, not the overall efficiency.


What is effIcency of a machine?

Efficiency is the common term for any thing. Usually we give input to perform an act and we derive some output because of that. As far as material machines are concerned definitely output power cannot exceed input power due to conservation of energy. Therefore the ratio of the output power to that of input is defined as efficiency of the machine. Usually it will be given in percentage by muliplying the decimal by 100.


Which factor increases as the efficiency of a machine increases?

The output work done by the machine increases as the efficiency of the machine increases. This is because efficiency is the ratio of useful work output to the total work input, so as efficiency increases, more of the input work is converted into useful output work.


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.

What percentage of energy is converted into useful energy?

It depends on the efficiency of the machine. No machine is perfect and there are always losses and waste. Usually the losses are a greater percentage than the useful energy.

What is the formula for efficiency of a machine?

useful energy output divided by total energy output x 100 give answer as a percentage, which is why you multiplied by 100


Is the efficiency of a machine calculated by the ratio or by the product?

The efficiency of a machine is calculated by the ratio of useful output work to the input work, typically expressed as a percentage. This ratio helps determine how well a machine converts input energy into useful work output.


What factor increases as the efficiency of a machine increases?

The output power of the machine increases as its efficiency improves. This means that more of the input energy is being converted into useful work, leading to higher output power.


Which factor increases as the efficiency of machine increases?

The output or work produced by the machine typically increases as the efficiency of the machine increases. This means that a higher proportion of the input energy is being converted into useful work output as the machine becomes more efficient.


Does a high-efficiency machine degrade a relatively high or low percentage of energy to thermal energy?

A high-efficiency machine degrades a relatively low percentage of energy to thermal energy. This means that a larger percentage of the energy input is converted into useful work or output, resulting in less wasted energy in the form of heat.
