A machine you designed has an efficiency of 60%. What happens to 60% of the work put into the machine, and what happens to the other 40%?
The 60% goes to do the work the machine is designed to do. The other 40% is lost to do the work and it goes out in the form of heat, light, etc.

When a machine has an efficiency of 60%, it means that 60% of the input work is converted into useful output work. The remaining 40% is lost as waste or dissipated in the form of heat, sound, or other forms of energy.
Specifically:
- 60% of the work put into the machine is converted into useful output work. This means that 60% of the input energy is transformed into the desired output, which could be mechanical work, electrical power, or any other form of work the machine is designed to perform.
- The other 40% of the work put into the machine is lost as waste or dissipated energy. This is typically referred to as energy loss, and it can occur due to various factors such as friction, electrical resistance, or other inefficiencies in the machine's design or operation.
In a more practical sense, if you were to input 100 joules of energy into a machine with 60% efficiency, 60 joules would be converted into useful work, while 40 joules would be lost as waste or dissipated energy.
When a machine is said to have an efficiency of 60%, it means that it can convert 60% of the input work into useful output work. The remaining 40% is lost as waste energy.
To understand what happens to the 60% of work that is converted into useful output, let's consider an example. Suppose you input 100 Joules of work into the machine. Based on the efficiency of 60%, the machine will convert 60 Joules (60% of 100) into useful output work.
The output work could be in various forms depending on the type of machine. For example, in a car engine, the output work could be the mechanical energy that moves the wheels. In an electric kettle, the output work could be the heat energy that boils the water.
Now, let's discuss the remaining 40% of the work. This portion of the input work is lost as waste energy. Waste energy in machines often takes the form of heat, friction, sound, or any other form of energy that is not useful for the intended purpose of the machine. Inefficient processes, such as friction between moving parts or resistance in electrical circuits, can contribute to this waste energy.
In summary, in a machine with 60% efficiency, 60% of the input work is converted into useful output work, and the remaining 40% is lost as waste energy.
