What is a machine with efficiency of less than one?

no machine has one


If the output work of a simple machine is than the input work the machine is said to have less than 100 percent efficiency?

input


Can any pulley have a efficiency over 100?

No. A perfectly frictionless machine could have an efficiency of 100%. Anything less perfect must have can efficiency less than 100%.


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.


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.


Why a high-efficiency machine is more desirable than a low- efficiency machine?

High-efficiency machines do more for less and are therefore more desirable than a low-efficiency machine.AnswerHigher efficiency means lower energy losses and, therefore, such machines are more economical than low-efficiency machines.


Describe why a high-efficiency machine is more desirable than a low-efficiency machine?

A high-efficiency machine consumes less energy to perform the same task as a low-efficiency machine, resulting in lower operating costs and reduced environmental impact. Additionally, high-efficiency machines often have longer lifespans and require less maintenance, leading to overall cost savings and improved reliability.


Explain why the amount of work that a machine does is less than the amount put into the machine?

The amount of work that a machine does is less than the input work due to energy losses in the form of friction, heat, and inefficiencies in the machine's operation. These losses result in some of the input work being dissipated and not translating fully into useful output work performed by the machine.


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


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 output work of a simple machine is than input work the machine is said to have less than 100 percent efficiency?

so wut exactly is ur question?


Does an ideal machine would have an efficiency greater than one?

No, an ideal machine would not have an efficiency greater than one. Efficiency is calculated as output divided by input, and it represents how well a machine converts input energy into useful work. An efficiency greater than one would imply that the machine produces more output energy than the input energy, which violates the conservation of energy principle.
