If the input work on a machine the machine has blank 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.
What is the formula of each simple machine by getting the work exerted by the machine?
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
How are input work and output work related?
Input work and output work are related by the sign. Example force F and Displacement D create work W;W = FD= -fdcos(FD) + 1FXD fdsin(FD)If the sign of the work is negative, the work is called output or ex-ergy; if the sign is positive the work is en-ergy or input work..There are two kinds of work, scalar work Cos(FD) and vector work or Torque sin(FD).
Which shows relationship between work input and work output?
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.
Equals the output work divided by the input work?
All machines lose some of the input force applied to them as a result of friction and other forces. The efficiency of a machine refers to how much of the input work is converted to output work by the machine. You can find the efficiency of a machine by dividing the output work by the input work. Because the output work will always be smaller than input work, efficiency will always fall somewhere between 0 and 1, with 1 being a machine that has as much output as input work (not possible in the real world) and 0 being a machine that is totally useless because none of the input work is converted to output work.
How do you find the mechanical efficiency of a pulley?
you have to do: work (output) divided by work (input) = F x d (output) divided by F x d (input)
The work output of a machine divided by the work input is the?
efficiency.
What is the definition of mechanical efficiency?
Output work divided by input work
What is defined as input work divided by output work?
-3/-45
What is the work output of machine divided by the work input called?
That is called the efficiency.
How do you calculate the mechanical efficiency of a machine?
Work output divided by Work input Times 100
If the input work on a machine the machine has blank 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.
What is a a comparison of a machines work output with the works input that is mechanical?
Output power divided by input power, for a machine, is called the machine's efficiency. It need not be mechanical energy.
What is the formula of each simple machine by getting the work exerted by the machine?
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
What is a comparison of a machine's work output and work input?
Output is always greater than input. The output is multiplied from input.
How are input work and output work related?
Input work and output work are related by the sign. Example force F and Displacement D create work W;W = FD= -fdcos(FD) + 1FXD fdsin(FD)If the sign of the work is negative, the work is called output or ex-ergy; if the sign is positive the work is en-ergy or input work..There are two kinds of work, scalar work Cos(FD) and vector work or Torque sin(FD).
