Input work is the work done on a machine, while output work is the work done by the machine. Efficiency of a simple machine is calculated as the ratio of output work to input work. The efficiency of a simple machine is high when the output work is close to the input work, indicating that the machine is converting most of the input work into useful output work.
If the input work equals the output work, the machine has 100% efficiency, meaning it is able to convert all the input work into useful output work without any losses. An efficient machine is desirable as it maximizes the output for a given input.
When a machine has an efficiency less than 100%, it means that not all of the input work is converted into output work. Some of the input work is lost as waste energy, usually in the form of heat or friction. This results in the output work being less than the input work applied to the machine.
mechanical efficiency
If the input work is processed by a machine and no output work is produced, the machine is considered to have zero efficiency. This means that the machine is not effectively converting input work into useful output work.
Output(input), or O(i)
Input work is the work done on a machine, while output work is the work done by the machine. Efficiency of a simple machine is calculated as the ratio of output work to input work. The efficiency of a simple machine is high when the output work is close to the input work, indicating that the machine is converting most of the input work into useful output work.
If the input work equals the output work, the machine has 100% efficiency, meaning it is able to convert all the input work into useful output work without any losses. An efficient machine is desirable as it maximizes the output for a given input.
Work Output is the work done BY a machine. Work Input is the work done ON a machine.
Work Output is the work done BY a machine. Work Input is the work done ON a machine.
When a machine has an efficiency less than 100%, it means that not all of the input work is converted into output work. Some of the input work is lost as waste energy, usually in the form of heat or friction. This results in the output work being less than the input work applied to the machine.
mechanical efficiency
Output is always greater than input. The output is multiplied from input.
If the input work is processed by a machine and no output work is produced, the machine is considered to have zero efficiency. This means that the machine is not effectively converting input work into useful output work.
Work input is work done on a machine to get the desired output. Work output is the amount of desired work that is done by a machine.
Input work refers to the work done on a machine, which is calculated as the input force multiplied by the input distance. Output work is the work produced by the machine, which is calculated as the output force multiplied by the output distance. The efficiency of a machine is determined by comparing the output work to the input work, with ideal machines having an efficiency of 100%.
If a machine has 100 percent efficiency, the output work = the input work. That's actually basically what the efficiency of a machine is - output work / input work * 100.
