What else can I help you with?
The efficiency of a machine is always less than 100 percent because?
some energy is always lost to factors like friction, heat, and sound during the operation of a machine, reducing its efficiency below 100%.
Does an ideal machine have an effciency of 100 percent?
No, an ideal machine cannot have an efficiency of 100 percent. This is because some energy is always lost as heat due to factors like friction and resistance. The best an ideal machine can achieve is an efficiency of 100% by having no energy losses.
Why is it impossible for a machine to give you more energy output than the amount of energy put into it?
It is impossible due to the principle of energy conservation, which states that energy cannot be created or destroyed, only transferred or transformed. Therefore, any machine or system will always output less energy than the amount of energy put into it. This limitation is known as the efficiency of the machine.
What is the relationship between friction and efficiency of a machine?
The relationship between friction and the efficiency of a machine is when friction increases, efficiency decreases, and vice versa. That is why you can never have 100% efficiency, because there is always at least a little friction. They are inversely proportional, meaning, higher friction equals less efficiency.
The mechanical advantage of a machine is always greater than 1?
well the advantage of that is pie, not math pie but pie that you eat
Why a normal machine could not have the mechanical efficiency of 100?
Because there is always going to be friction, the efficiency of any machine will always be less then 100 percent.
The efficiency of a machine is always less than 100 percent because?
some energy is always lost to factors like friction, heat, and sound during the operation of a machine, reducing its efficiency below 100%.
How does effieciency of the machine affects it's performance?
if a machine is not efficient, it cannot fully utilise its performance. actual performance = efficiency x possible performance efficiency = actual performance / possible performance efficiency is always a decimal number less than 1, as no machine is perfect in terms of efficiency
Does an ideal machine have an effciency of 100 percent?
No, an ideal machine cannot have an efficiency of 100 percent. This is because some energy is always lost as heat due to factors like friction and resistance. The best an ideal machine can achieve is an efficiency of 100% by having no energy losses.
Can a machine's efficiency can be greater than 100 percent?
nope, efficiency o fa machine cannot be greater than 100%...theoretically it shows sometime that efficiency of a machine can be 100%, but practically it cannot be possible as there is some loss of energy is always involved in different ways.
Why is it impossible for a machine to give you more energy output than the amount of energy put into it?
It is impossible due to the principle of energy conservation, which states that energy cannot be created or destroyed, only transferred or transformed. Therefore, any machine or system will always output less energy than the amount of energy put into it. This limitation is known as the efficiency of the machine.
What is the Formula for calculating the efficiency of a machine?
Efficiency = Output value / Input valueFor example, if a machine needs 10 KW to run and produces 8 KW, its power efficiency is 8/10 = 0.8 or 80%Efficiency is always between 0 and 1 (or 0 and 100 if expressed as a percentage.)
What is the relationship between friction and efficiency of a machine?
The relationship between friction and the efficiency of a machine is when friction increases, efficiency decreases, and vice versa. That is why you can never have 100% efficiency, because there is always at least a little friction. They are inversely proportional, meaning, higher friction equals less efficiency.
What is meant by efficiency of a machine?
It is the output energy compared to the input energy. This will always be less than 100%
The mechanical advantage of a machine is always greater than 1?
well the advantage of that is pie, not math pie but pie that you eat
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.
Why the efficiency of a machine is always less than 100?
The efficiency of a machine is always less than 100% due to energy losses that occur during its operation. These losses can result from factors such as friction, heat generation, and air resistance. No machine can convert all input energy into useful work without some energy being lost as waste.
