Work Output is the work done BY a machine. Work Input is the work done ON a machine.
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.
The relationship between work input and work output is defined by the efficiency of a system. Efficiency is a measure of how well a system converts input work into output work and is calculated as the ratio of output work to input work. A higher efficiency indicates a more effective conversion of work input to work output.
Work Input = Work Output + Work done in overcoming friction.Therefore Work Input > Work Output.
Work Output is the work done BY a machine. Work Input is the work done ON a machine.
The comparison between output and input work is called efficiency. It is a measure of how well a system can convert input work into useful output work. Efficiency is usually expressed as a percentage, with 100% being perfect efficiency.
The relationship between input work and useful output work can be represented by efficiency. Efficiency is the ratio of useful output work to input work. A higher efficiency indicates that a larger proportion of the input work is converted into useful output work, while a lower efficiency suggests that more of the input work is wasted or converted into non-useful forms.
Work input is what you do in labor to get the job done. Work output is what you get from the work. Take farming for example: you plant seeds (that's the work input) and when it grows corn that's the output.
Output is always greater than input. The output is multiplied from input.
The formula for work exerted by each simple machine is: Lever: Work = Input force × Input distance = Output force × Output distance Inclined plane: Work = Input force × Input distance = Output force × Output distance Pulley: Work = Input force × Input distance = Output force × Output distance Wheel and axle: Work = Input force × Input radius = Output force × Output radius Wedge: Work = Input force × Input distance = Output force × Output distance Screw: Work = Input force × Input distance = Output force × Output distance
The formula to find the work output of efficiency is: Work output = Efficiency x Input work. Efficiency is a ratio of output work to input work, so multiplying this ratio by the input work gives the work output.
The output work of a machine is typically less than the input work, due to factors such as friction, heat loss, and other inefficiencies in the machine's operation. This difference between input and output work is known as the efficiency of the machine.
When calculating efficiency, work input is compared to the work output. Efficiency is the ratio of the work output to the work input, expressed as a percentage. It shows how effectively a system converts input energy into useful output energy.
