What does the term efficiency of machine' means?
The efficiency of a machine refers to how well it converts input energy into useful work output. It is a measure of how effectively the machine minimizes waste and maximizes its output relative to its input. Higher efficiency means less energy loss during the machine's operation.
The efficiency of a machine is defined as?
The efficiency of a machine is a measure of how well it converts input energy into useful work output. It is calculated as the ratio of useful work output to the total input energy or power. A high efficiency indicates that the machine is able to minimize energy losses and perform its intended function effectively.
If the input work on a machine is equal to its output work the machine has efficiency?
Yes, that's correct. Efficiency is a measure of how well a machine converts input work into output work. If the input work equals the output work, then the machine is considered 100% efficient.
How is the efficiency of a compound machine calculated?
The efficiency of a compound machine is calculated by dividing the output work of the machine by the input work. Mathematically, it can be expressed as Efficiency = (Output work / Input work) * 100%. It gives a measure of how well the machine converts input work into useful output work.
What is the ability of a machine to convert input work into output work?
The ability of a machine to convert input work into output work is known as mechanical efficiency. It is a measure of how well a machine can transform energy while minimizing waste in the form of heat, sound, or friction. A higher mechanical efficiency means that more of the input work is converted into useful output work.

A higher mechanical efficiency means that more of the input work is converted into useful output work.
Is the efficiency of a machine is 60 the percentage of work input used to overcome friction?
No, efficiency of a machine is a measure of how well input energy is converted into useful output work, and is calculated as useful work output divided by total work input. The percentage of work input used to overcome friction would be related to the frictional losses in the machine, not the overall efficiency.
How does the output work compare to the input work for a machine that has an efficiency less than 100?
For a machine with efficiency less than 100%, the output work will always be less than the input work. This is because some of the input work is lost as waste energy due to factors like friction, heat, or other inefficiencies in the machine. The efficiency of a machine is a measure of how well it converts input work into useful output work.
Does a machine with an efficiency of 1.2 requires a smaller effort force than a machine that has an efficiency of 2.2?
Efficiency is a measure of power losses. A machine with an efficiency of say 85% or 0.85, experiences 15% power losses from input to output (as heat through friction) This would be typical for say a car, comparing crankshaft power to power at the drive wheels. No machine will exceed 100% efficiency > Work done = force * distance Efficiency = work done at output / work done at input > Mechanical Advantage (leverage) is distance moved by input / distance moved by output. Output force = input force * Mechanical Advantage
Is the lower the percent of energy required for a machine to perform work the more efficient it is?
Yes, the lower the percentage of energy required for a machine to perform work, the more efficient it is. Efficiency is a measure of how well a machine converts input energy into useful work output, so a lower energy requirement indicates a higher level of efficiency.
Can you give me another word for effectively?
It is best given in an example describing how a machine or service works. Effectively, this is how it operates - could be changed to.... Well, this is how it operates or... In actual fact, this is how it operates.
If the output work of a simple machine is than input work the machine is said to have less than 100 percent efficiency?
No, a simple machine with less output work than input work is said to have less than 100 percent efficiency. Efficiency is a measure of how well a machine converts input work into output work, with 100 percent efficiency meaning that all input work is converted to useful output work.
