When a machine is running at 100 % efficiency there is no loss of energy anywhere. That means the machine is running silently and if turned off will continue to run without stopping. In the real world there is sound and there is friction. Both sound and friction are examples of less than perfect efficiency

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 effect does friction have on a machines efficiency?
Friction can reduce a machine's efficiency by causing energy loss in the form of heat and sound. This can result in increased wear and tear on the machine, leading to reduced performance and potentially higher energy consumption. Minimizing friction through lubrication and proper maintenance can help improve a machine's efficiency.
Does an ideal machine have friction?
No, an ideal machine is usually considered to be frictionless to simplify calculations and convey fundamental concepts. In reality, all machines have some level of friction, which can reduce efficiency and introduce energy losses.
How does friction reduce the efficiency of machines?
Friction is cased by parts of the machine rubbing past one another. When this happens the parts tend to stick to each other which slows down the machine and heats up the parts. Thus the energy used to drive the machine is diverted from the purpose for which the machine was constructed and the machine becomes less efficient. To reduce friction and make the machine more efficient, lubricants (eg oil) are used to make sure that parts that come into contact can slide past one another more easily. -------------------------------------------------------------------------------- Friction causes machines to slow down, and heat up. effecting efficiency negatively first off excess causes a decrease in speed increase in wear on parts. Also friction causes heat which causes metals to expand. For optimal mechanical efficiency, friction is the enemy. ------------------------------------------------------------------------------------ Friction decreases efficiency. This is because when there is friction, heat is created. Therefore some energy is lost in the form of heat.
Friction is not related to the efficiency of a machine true?
False. Friction can significantly affect the efficiency of a machine by causing energy losses and reducing its overall performance. Minimizing friction through proper lubrication and design can help improve the efficiency of a machine.

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.

What limits the efficiency of machine?
friction
What can you do to increase the efficiency of a machine?
Reduce losses from friction so forth in transmission of power. Ensure fuel utilized to the fullest.

What role does friction have in reducing mechanical efficiency?
Friction is the reason that you can never have a 100% efficient machine. It is the reason that most machine have horrible efficiency.

Which force reduces the efficiency of machine?
Friction.
How do you reduce the friction in a machine?
Oil it
How could you use friction to make a machine more efficient?
You can use friction to your advantage by strategically placing it in parts of a machine where it can help with the transfer of energy, such as in bearings or gear mechanisms. By carefully controlling and optimizing the amount of friction in these components, you can reduce energy loss and improve the overall efficiency of the machine.
