it is the amount of work that can be done. a machine can use 300,000 J of energy but it only uses 263,000 J. that is percent efficiency.
99.4%
The efficiency of a pulley system depends on how it is set up. Be specific.
Cuz nuffin is purfect
yes
an ideal machine
nothing has 100% efficiency.
Perhaps an electrical AC transformer can have 99 percent efficiency. A loudspeaker can have only 1 percent efficiency.

The laws of thermodynamics imply that there will always be some loss of efficiency.
It is not a good efficiency engine.
The efficiency of a pulley system depends on how it is set up. Be specific.
mechanical efficiency is the percent of the energy that you put into a machine that was transferred to the load.
Efficiency is normally written as a percentage, and does not have an SI unit."percent". It has no units.
No. Nothing mechanical can ever have a 100% efficiency by any physical evaluation.
It is not a good efficiency engine.
