How is a machine's efficiency of a calculated?
Efficiency = useful output power / input power
How can a machine's efficiency be calculated?
Machine efficiency can be calculated by dividing the useful output of the machine by its total input, and then multiplying by 100 to express it as a percentage. Useful output could be output energy, work done, or products manufactured, while total input includes energy or fuel consumed. The formula for efficiency is: Efficiency = (Output/Input) x 100%.
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 a specific example of a machine and describe how its mechanical efficiency might be calculated?
An example of a machine is a car engine. Mechanical efficiency can be calculated by comparing the work output (such as the power produced by the engine) to the work input (such as the energy from the fuel). The formula for mechanical efficiency is: Efficiency = (useful work output / total work input) x 100%.
What is the mechanical efficiency of a machine that produces 400 joules of work output from work input of 500 joules?
The efficiency is 80%. To find the efficiency, 400/500 = 80%.
How is the efficiency of a machine calculated?
Efficiency = useful output power / input power
How much efficiency does a compound machine have?
The decimal efficiency of each part multiplied together.
What is efficiency and how is it calculated?
The efficiency is output divided by input.
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.
How is a machine's efficiency of a calculated?
Efficiency = useful output power / input power
How do you calculate the efficiency of a machine?
Efficiency is nothing but calculating how the machine is performing for what it has been made for, Efficiency is usually calculated in % as (output/input )X100. for Eg. the Thermal efficiency of an reciprocating gasoline engine can be calculated as follows, Let, the input for an reciprocating engine is 12MJ and its out put is 4MJ then Efficiency is (4/12)X100 = 33%

What do you need to know to calculate the efficiency of a machine?
To calculate the efficiency of a machine, you need to know the amount of useful work output produced by the machine and the amount of total energy input supplied to the machine. Efficiency is calculated by dividing the useful work output by the total energy input and multiplying by 100 to express it as a percentage.
What must you know in order yo calculate a machine's efficiency?
To calculate a machine's efficiency, you need to know the input energy (total energy put into the machine) and the output energy (useful energy the machine produces). Efficiency is usually calculated as the output energy divided by the input energy, multiplied by 100 to get a percentage.
