∙ 15y agoEfficiency is simply, the ratio of the output to the input of any system .That is, the amount of energy produced that is converted into work [Work =Force X Displacement] For example, a combustion engine produces alot of energy but mostly in the form of heat and noise.Only ~25% of the energy trapped in the hydrocarbon bonds is concverted from chemical to mechanical energy.Therefore, it has an efficiency of roughly 25%. So efficiency of machines is the actual work they do in relation to the total amount of power they produce.
Factors that can limit the efficiency of a machine include friction between moving parts, heat loss during operation, mechanical wear and tear, and lack of proper maintenance. Inefficient design and suboptimal operating conditions can also impact the overall efficiency of a machine.

Efficiency is always less than 100% due to the friction. So therefore efficiency of a machine is always affected by a friction

What are the factor that affect the efficiency of simple machine?
Factors that can affect the efficiency of a simple machine include friction, mechanical losses, wear and tear, misalignment, and material properties (such as strength and durability). Proper maintenance and lubrication can help improve efficiency by reducing these factors.
How do you determine machine efficiency?
Machine efficiency is typically determined by calculating the ratio of useful output to input. This can be done by comparing the actual output of the machine to its theoretical maximum output under ideal conditions. Factors such as energy losses, downtime, and maintenance can also affect machine efficiency.
What is an obstacle to 100 efficiency for a real machine?
Friction is a common obstacle to achieving 100% efficiency in a real machine. Friction causes energy to be lost as heat, reducing the overall efficiency of the machine. Additionally, imperfections in materials, wear and tear, and other factors can also contribute to inefficiencies.
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%.
The output work of a machine compared to the input work is?
The output work of a machine is typically less than the input work, due to factors such as friction, heat loss, and other inefficiencies in the machine's operation. This difference between input and output work is known as the efficiency of the machine.

Why is no machine 100 percent eficent?
No machine can be 100% efficient due to factors such as friction, heat loss, and external factors that affect performance. These limitations result in energy being lost or wasted during the operation of the machine, reducing its overall 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.
Why is a high efficiency machine is more desirable than a low efficiency machine?
A high efficiency machine will produce more of what is it that you want with the same power as the low efficiency one. In other words, for a low efficiency machine do as much as a high efficiency one, you have to give it more power (energy).
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 do you mean by the efficiency of a simple machine is 85 percent?
When the efficiency of a simple machine is 85 percent, it means that 85 percent of the input work is converted into useful output work, while the remaining 15 percent is lost due to factors like friction and heat. This efficiency percentage gives an idea of how effectively the machine is performing its intended task.
What is the maximum efficiency of a machine?
The maximum efficiency of a machine is 100%, which means that all input energy is converted into useful output energy without any losses. However, achieving 100% efficiency is practically impossible due to factors such as friction, heat loss, and other inefficiencies in real-world systems.
How is a real machine and an ideal machine different?
A real machine is a physical device with moving parts that may have friction and energy losses, resulting in reduced efficiency. An ideal machine is a theoretical concept that assumes no energy losses due to friction or other factors, resulting in 100% efficiency. Ideal machines are used for theoretical calculations and comparisons, while real machines consider practical limitations and inefficiencies.
