At least my oppinion without any garantuee: There can be a negative efficiency for example in the case of induction motors driver by inverter and FOC in generator mode. Since you have an induction motors you always have to provide some power in order to magnetize the rotor. The current which magnetizes the rotor causes losses. So there could be some working points where the losses caused due to the magnetization are bigger than the power generated (the negative torque taken away from the rotor).

Output work divided by input work
Attainable and the economy is efficient. The line is actually where one would produce at maximum efficiency if it were possible to work at perfect effociency. Although, since we are human and make mistakes, it is impossible for anyone to work at the maximum efficiency.
An example of how division of work can improve efficiency in a team project is when each team member is assigned specific tasks based on their strengths and expertise. This allows for work to be completed more quickly and effectively, as each person can focus on their assigned responsibilities without overlapping or duplicating efforts.
Efficiency effectiveness can only be measured by results; cost efficiency, time efficiency, output efficiency, etc.
I think it is efficiency.;)
The consequences of negative work done on a system can include a decrease in the system's energy, a decrease in the system's temperature, and a change in the system's state or properties. Negative work typically represents work done by the system on its surroundings, resulting in a loss of energy within the system. This can lead to a decrease in the system's overall performance or efficiency.
Efficiency % = (work out / work in) * 100 (Work = force * distance)
Efficiency % = (work out / work in) * 100 (Work = force * distance)
The formula to find the work output of efficiency is: Work output = Efficiency x Input work. Efficiency is a ratio of output work to input work, so multiplying this ratio by the input work gives the work output.
To find the work out, you can use the formula for efficiency: Efficiency = (Work out / Work in) * 100. Given that the efficiency is 95%, you can rearrange the formula to find Work out as follows: Work out = (Efficiency / 100) * Work in. Substituting the values, you get Work out = (0.95) * 95 J = 90.25 J.
efficiency
Spring efficiency is calculated by dividing the work output of a spring by the work input. It is expressed as a ratio or percentage, with higher values indicating better efficiency. The formula is: Efficiency = (Work output / Work input) x 100%.
Mechanical efficiency is determined by dividing the output work by the input work, while thermal efficiency is calculated by dividing the useful work output by the heat input. Relative efficiency is the ratio of mechanical efficiency to thermal efficiency and can be used to compare the effectiveness of a machine in converting input energy to useful work.
The output work done by the machine increases as the efficiency of the machine increases. This is because efficiency is the ratio of useful work output to the total work input, so as efficiency increases, more of the input work is converted into useful output work.
The efficiency is 80%. To find the efficiency, 400/500 = 80%.
Efficiency = useful output power / input power
