No, we don't find the output force of a system is greater than its input. We've never seen this. There are losses associated with any system, whether they be mechanical, thermal or other. That prevents a situation where we can get more energy out of a system than we put in.
We don't know all there is to know about physics, but we know a lot. If we knew how to get more energy out of a system than we put into it, we'd have applied that to generate electrical power. Consider how we provide electricity ot the power grid now and think it through to confirm the idea that we don't know of a way to get more energy out of a system than we put in. Perpentual motion isn't something we've realized, either.

Why input current of USis less than Output current?
Why input current of USis less than Output current?
What is current gain and voltage gain?
Current gain is the ratio of output current divided by input current. Voltage gain is the ratio of output voltage divided by input voltage. Nothing more complicated than that.
Input impedance is greater than to load impedance?
In electronic gears we use voltage bridging, that is a relative low output impedance to a higher input impedance. Usualy the input impedance is more than ten times higher then the output impedance.An input impedance is called also a load impedance or an external impedance.An output impedance is called also a source impedance or an internal impedance.
How does beta factor affects the transistor?
Beta is current gain of that transistor,whatever be the input the trasistor. we will get the output multiplied by the beta. for example in CE amplifer if Base current is 10 microampere and beta of that transistor is 100 then collector current would be 1mA i.e. 100 times greater than input current
Why might the unloaded output voltage of a transformer be higher than its rms of 12.6v?
Because the windings of transformers have resistance, the primary and secondary currents will cause voltage drops. To compensate for the drops, the transformer may have been designed to have a higher than specified output voltage when there is little or no output current. The no load output voltage typically is only slightly greater than the specified voltage. Before measuring the output voltage, measure the input (line) voltage. If it is not as specified for the transformer, calculate its effect on the output.
Why input current of USis less than Output current?
Why input current of USis less than Output current?
If a machine has a mechanical advantage much greater than 1 how will the output force be in comparison to the input force?
The Output Force Will Most Likely Be Greater Than The Input Force. So "OUTPUT" Is Greater Than "INPUT".
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.
Is the output distance always greater than the input distance?
No, the output distance is not always greater than the input distance. It depends on the specific situation and factors involved.
The output force of a rake is greater than the input force?
This is possible when using a lever system with the rake, where the input force is applied over a shorter distance but results in a greater output force over a longer distance. The mechanical advantage gained from the lever system allows for the output force to be greater than the input force in this scenario.
Is it possible for energy output to be greater than energy input?
No.
Work output can never be greater than?
Work input.
Why is output dc higher than input ac?
Output power can never be more than input power. With a transformer, it is possible to increase the output current (while decreasing the output voltage), or to decrease the output current (while increasing the output voltage).
If you exert an input force over a greater distance than the distance exerted by the output force for an ideal machine compare the size of the input and output forces.?
In an ideal machine, if you exert an input force over a greater distance than the output force, the input force will be smaller than the output force. This is because work input is equal to work output in an ideal machine, and work is calculated as force times distance. Therefore, if the input force acts over a greater distance, the output force must be larger to balance the work done.
Is energy input usually greater than energy output?
In general, no – energy input is not usually greater than energy output. In a closed system, energy is conserved, meaning that the total amount of energy remains constant. However, in real-world systems, there may be inefficiencies or losses that result in some energy input being converted into forms that are not useful as output.
Why is output work sometimes greater than input work?
Output work can be greater than input work when there are efficiency gains in the process, such as using better technology or methods that allow for more output with the same input. Additionally, output work can also be greater than input work when energy is added to the system from an external source, like in the case of a machine or equipment.
Can you make work output of a machine greater then the work input?
No. And you cannot make it greater THAN the input, either.
