Why is the output work in a machine always less than the input work?
Every real machine is subject to forces that reduce output. These include actual forces such as friction, or human controlled forces such as imperfect machining. This reduces the output to less than the ideal.
What is a ballistocardiogram?
A ballistocardiogram is the visual output of a ballistocardiograph - a machine which measures ballistic forces on the heart.
How is the efficiency of a compound machine calculated?
The efficiency of a machine is found by dividing the amount of work done by a machine by the amount of energy used by a machine. The answer is then multiplied by 100 to give a percentage.
A broom is an example of a machine. where are the input and output forces applied?
The applied force to the end of the handle is the input force and the output force is when the broom sweeps over the floor.
How lubricating a machine affects the output?
Lubricating a machine affects the output force exerted by the the machine by allowing more movement because the more movement means more output.
Why is the output work in a machine always less than the input work?
Every real machine is subject to forces that reduce output. These include actual forces such as friction, or human controlled forces such as imperfect machining. This reduces the output to less than the ideal.
What are input and output forces?
An input force is what force you act upon a machine. The output is what it does for you in return.
In a real machine why is the work output always less than the work input?
Every real machine is subject to forces that reduce output. These include actual forces such as friction, or human controlled forces such as imperfect machining. This reduces the output to less than the ideal.
In a real machine the work output is always less than the work input.?
Every real machine is subject to forces that reduce output. These include actual forces such as friction, or human controlled forces such as imperfect machining. This reduces the output to less than the ideal.
How does a simple machine affect force output?
A machine is a device for multiplying forces or simply changing the direction of forces. Underlying every machine is the conservation of energy
In a compound machine made up of two simple machines how is the work output of the first simple machine related to the work input of the second simple machine?
The work ouput of the second machine will usually be more than the work input of the first machine.
What is a ballistocardiogram?
A ballistocardiogram is the visual output of a ballistocardiograph - a machine which measures ballistic forces on the heart.
How do you calculate the mechanical advantage of any machine if you only know the forces?
The ratio of the output to input forces may help you there.
A broom is an example of machine where are the input and output forces applied?
The applied force to the end of the handle is the input force and the output force is when the broom sweeps over the floor.
How is the efficiency of a compound machine calculated?
The efficiency of a machine is found by dividing the amount of work done by a machine by the amount of energy used by a machine. The answer is then multiplied by 100 to give a percentage.
Mechanical advantage of a compound machine?
MA = Revolutions of input shaft / Revolutions of output shaft. (Input torque * MA) * efficiency = Output torque Note 100% efficiency = 1.0
A broom is an example of a machine. where are the input and output forces applied?
The applied force to the end of the handle is the input force and the output force is when the broom sweeps over the floor.
