What is the name of the machine of the force that prevents machines from operating at 100 percent efficiency?

The machine is called a governor. It regulates the speed and performance of machines to prevent them from operating beyond their design limits, protecting them from damage and ensuring stability.


What machine on earth has the greatest percentage of efficiency?

Perhaps an electrical AC transformer can have 99 percent efficiency. A loudspeaker can have only 1 percent efficiency.


How does the output work compare to the input work for a machine that has an efficiency equal to 100 percent?

If a machine has 100 percent efficiency, the output work = the input work. That's actually basically what the efficiency of a machine is - output work / input work * 100.


What would a machine that had 100 percent mechanical efficiency be called?

A machine with 100 percent mechanical efficiency would be called an ideal machine, as it would have no energy losses due to friction, heat, or other inefficiencies.


What is the mechanical efficiency of a machine whose work input is 100j and work output is 30j?

The mechanical efficiency of this machine is 30 percent.


What is mechanical efficiency in science?

mechanical efficiency is the percent of the energy that you put into a machine that was transferred to the load.


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 of the machine compares the output work to the input work and is expressed as a percent?

That's the machine's "efficiency".


Why a normal machine could not have the mechanical efficiency of 100?

Because there is always going to be friction, the efficiency of any machine will always be less then 100 percent.


A machine has an efficiency of 91 percent If the energy supplied to the machine is watts what is the amount being used for work?

If the efficiency is 91%, then work = 0.91 times watts


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.
