If you know the input distance and output distance of a machine which of the following can you calculate?
Type your answer here... The actual mechanical advantage.
If a simple machine provide sn increased output force what happens to the output distance?
If a simple machine provide an increased output force, then the the distance from the load to the pivot needs to be increased.
What quantity measures the output force of a machine relative to the input force?
Efficiency.
The efficiency of a real machine?
Efficiency is equal to the ratio of work input to work output; for an ideal machine this ratio is equal to 1 or 100%. For a real machine this ratio is always less than 1 because some of the work input is used to overcome mechanical friction within the machine which does not contribute to the work output of the machine.
Number of times that a machine increases the input force?
Increasing the distance between the load and pivot increases the work output of a machine.
How do you calculate work output for a simple machine?
The resistance force multiplied by the resistance distance.
If you know the input distance and output distance of a machine which of the following can you calculate?
Type your answer here... The actual mechanical advantage.
What do you need to know to calculate the mechanical advantage of a compound machine?
torque in * input rpm/output rpm = torque out
If a simple machine provide sn increased output force what happens to the output distance?
If a simple machine provide an increased output force, then the the distance from the load to the pivot needs to be increased.
What quantity measures the output force of a machine relative to the input force?
Efficiency.
Formula to calculate work output?
Work Output=Resistance X Distance
If you know the input distance and the output distance what can you calculate?
Actual Mech. Advantage
How do you calculate total vaiable cost per unit?
Total Variable Cost divided by Quantity of Output
What is force distance trade off in a simple machine?
That means that if you use a simple machine to apply less force, you need to compensate by applying the force over a larger distance - for example, to lift up a weight or do some other work.
What is the definition of output and input work?
Work Input- The work done on a machine as the input force acts through the input distance. Work Output - The work done by a machine as the output force acts through the output distance (What the machine does to the object (dependent on the force) to increase the output distance).
How do you calculate the mechanical efficiency of a machine?
Work output divided by Work input Times 100
Explain efficiency and how to calculate it for different simple machines?
Efficiency means to calculate that is the machine is efficient enough to save your bill or use less electricity. To calculate the formula is:Efficiency = Energy output (what is the machine producing) divided by Energy input (what is the machine taking or using).
