The mechanical advantage (MA) is usually less than the ideal mechanical advantage (IMA) for a machine due to factors such as friction, inefficiencies in the machine's design, and energy losses through heat or sound. These factors cause the input work to be greater than the output work, resulting in a lower actual mechanical advantage compared to the ideal mechanical advantage.
As the efficiency of a machine increases, the output of the machine for a given input also increases. This means that the machine can do more work with the same amount of energy input. Additionally, the operating costs of the machine may decrease as efficiency improves, since less energy is wasted.
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.
In a practical machine, energy losses occur due to factors such as friction, heat, sound, and vibration. These losses result in the power output being less than the power input, in accordance with the law of energy conservation. The dissipated energy usually ends up as waste heat, reducing the efficiency of the machine.
Yes, a machine can still be useful even if its mechanical advantage is less than one. This can happen when the machine reduces the amount of force needed to perform a task, even though the output force is less than the input force. An example of this is a pulley system, where the force needed to lift an object is reduced by distributing the load over multiple ropes and pulleys.

It is usually unavoidable that some energy is wasted.
Those who are given much recognition on earth will be of less importance in heaven. and those who are given least recognition will have greater recognition in heaven.
As the efficiency of a machine increases, the output of the machine for a given input also increases. This means that the machine can do more work with the same amount of energy input. Additionally, the operating costs of the machine may decrease as efficiency improves, since less energy is wasted.
Efficiency means to calculate that is the machine is efficient enough to save your bill or use less electricity. To calculate the formula is:Efficiency = Energy output (what is the machine producing) divided by Energy input (what is the machine taking or using).
That is becasue no machine is 100% efficient - SOME energy usually gets wasted.

A robotics is a user defined programmable machine which is very efficient in performing the tasks given by the user according to the instructions given to the machine. The performance of these machines are very efficient and takes very less time to perform the given task when compare to the normal human.
no machine has one
input
When a machine has an efficiency less than 100%, it means that not all of the input work is converted into output work. Some of the input work is lost as waste energy, usually in the form of heat or friction. This results in the output work being less than the input work applied to the machine.
