Increasing the efficiency of a simple machine means that it requires less input work to produce the same output work. This results in less wasted energy and ultimately allows the machine to do more work with the same amount of input.
Increasing the input force or the distance over which the force is applied can increase the work output of a simple machine. Reducing friction within the machine can also help to increase its efficiency and work output.
Input work is the work done on a machine, while output work is the work done by the machine. Efficiency of a simple machine is calculated as the ratio of output work to input work. The efficiency of a simple machine is high when the output work is close to the input work, indicating that the machine is converting most of the input work into useful output work.
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.

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.
Increasing the input force or the distance over which the force is applied can increase the work output of a simple machine. Reducing friction within the machine can also help to increase its efficiency and work output.
Efficiency % = (work out / work in) * 100 (Work = force * distance)
Efficiency % = (work out / work in) * 100 (Work = force * distance)
Input work is the work done on a machine, while output work is the work done by the machine. Efficiency of a simple machine is calculated as the ratio of output work to input work. The efficiency of a simple machine is high when the output work is close to the input work, indicating that the machine is converting most of the input work into useful output work.
A fulcrum is a part of a simple machine, the lever. Without the fulcrum what is left of the simple machine can no longer increase the applied force and is no longer a 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.
What is the ‘cost’ for using a machine to increase force
In that case, the efficiency is said to be 1 - or equivalently, 100%.
The mechanical advantage of the machine is"if you give small accelration , it will increase the speed of the engine... It is possible by mechanical
