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.
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.
Does a machine with an efficiency of 1.2 requires a smaller effort force than a machine that has an efficiency of 2.2?
Efficiency is a measure of power losses. A machine with an efficiency of say 85% or 0.85, experiences 15% power losses from input to output (as heat through friction) This would be typical for say a car, comparing crankshaft power to power at the drive wheels. No machine will exceed 100% efficiency > Work done = force * distance Efficiency = work done at output / work done at input > Mechanical Advantage (leverage) is distance moved by input / distance moved by output. Output force = input force * Mechanical Advantage
Is work output always equal to work input?
Yes the only thing a machine changes is force,distance or direction
How do you calculate work output for a simple machine?
The resistance force multiplied by the resistance distance.
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.
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
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).
What is the efficiency of the machine?
a machine applies a force of 100 newtons over a distance of 10 meters to raise a500 newtons drum 1.5 meters. what is efficiency of the machine ?
What is the force exerted by a machine?
Work, which = Force x Distance (yes there is actually a formula).
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.
