How the efficiency of a ideal machine compares with the efficiency of a real machine?
In an ideal frictionless system, the work input equals the output and force. Your Welcome!!!
Does an ideal machine have an effciency of 100 percent?
No, there is not such thing as an ideal machine; it's just an idea.
The efficiency of an ideal machine is 100 percent. Do any machines used in your daily life in ideal Give reason to support your answer?
No physical machine is ideal. Friction is always a loss of energy.
Why doesn't any system have 100 percent efficiency?
frictionIn real machines, as opposed to ideal machines, there is always friction that reduces the efficiency of the machine. Lubricants like oil can be used to reduce friction and improve efficiency.
Is a ideal machine has an efficiency of less than one equal to one greater than one?
ideal machines have mechanical efficeincy equal to 1 (100% efficient) since efficiency is the ratio of the power output to the power input
What is the difference between a ideal machine and real machine?
In ideal machine input is equal to output . The efficiency of ideal machine is 100% . In real machine input is not equal to output .The efficiency of ideal machine in not 100% . In ideal machine there is no lose of energy . In real machine there is lose of energy . In real machine there is no friction . While in real machine there is friction .
How is a real machine and an ideal machine different?
An ideal machine can reach 100% efficiency as there is no friction or other restraints involved, whereas a real machine can never reach 100% efficiency.
Explain how much efficiency of an ideal machine compares with the efficiency of a real machine?
An ideal machine has, by definition, an efficiency of exactly 100%, which means that absolutely none of the energy it consumes is wasted when converted to power (energy per unit of time), hence the name "ideal". A real machine, however, will never reach an efficiency of 100%, as there will always be at least a tiny bit of energy that is lost to the environment. This is because it is practically impossible to create a perfectly closed system in which no energy can leak out. It is possible, however, to build very efficient systems and machines, although this depends on just how well they are made. Therefore, the efficiency of a real machine is quite variable, going easily from 10% to 98%, depending on its quality. A simple example is that of ordinary household voltage transformers, which generally have efficiencies of around 80%; and of high grade power plant transformers, which have efficiencies of around 98%.
What would a machine that had 100 percent mechanical efficiency be called?
an ideal machine
An ideal machine would have an efficiency of?
A ideal machine would have an efficiency of 100 percent. For this to be possible, the amount of energy output by the machine would equal the amount of energy input. Because all machines have physical parts, some energy is lost to friction, heat dissipation, or other factors, so no machine can be an ideal machine.
The efficiency of a machine is usually expressed in?
The efficiency of a machine is usually expressed as a percentage. The ideal efficiency of a machine is 100-percent.Another AnswerThere are no units of measurement for efficiency, because you are comparing like with like: output power divided by input power.
What is the difference between an ideal machine and a real machine?
In ideal machine input is equal to output . The efficiency of ideal machine is 100% . In real machine input is not equal to output .The efficiency of ideal machine in not 100% . In ideal machine there is no lose of energy . In real machine there is lose of energy . In real machine there is no friction . While in real machine there is friction .
