Type your answer here... Each and every mechanical work can be done by his....
The work done by a force in a mechanical system is called mechanical work. It is the transfer of energy when a force acts on an object to move it over a distance. Work is calculated as the product of the force applied and the distance moved in the direction of the force.
The energy used to turn a bolt with a screwdriver is mechanical energy. This mechanical energy is converted from the work done to rotate the bolt, transferring energy from the screwdriver to the bolt.
When mechanical work is done on a system, there is an increase in the system's internal energy. This increase in internal energy is due to the transfer of energy from the mechanical work applied to the system.

When mechanical work is done, the internal energy of a system can change. If work is done on the system, the internal energy increases. Conversely, if work is done by the system, the internal energy decreases. This change in internal energy is governed by the first law of thermodynamics.
Mechanical energy is the ability to do work. Work is done when a force acts on an object to move it over a distance. The work done on an object can change its mechanical energy, either increasing it if work is done on the object, or decreasing it if work is done by the object.
When you lift a stool, you are mainly using mechanical energy. This involves the work done by your muscles to raise the stool against the force of gravity.
work output
The work done on a machine is called input work or mechanical work. It refers to the energy transferred to the machine to operate it and perform tasks.
The work done by the Earth on the space station is zero since the force of gravity is perpendicular to the motion of the space station. This means that there is no displacement in the direction of the force, and thus no work is done.
