For flexibility or movement. For example most of our bodies joints have a mechanical disadvantage for the simple reason we gain range of motion and flexibility.
Mechanical pliers are pliers that are used in mechanical jobs, like fixing motor parts, auto parts, machines , etc.
Not all machines have motors. While many machines, especially those designed for mechanical work or movement, utilize motors to convert electrical energy into mechanical energy, there are machines that operate without motors, such as simple machines like levers, pulleys, or inclined planes. Additionally, some machines may rely on manual operation or other forms of energy, such as hydraulic or pneumatic systems, rather than using motors.
From Wikipedia, Mechanical is often used as a general term to distinguish from another class of item. Mechanical may mean:Mechanical engineering, a branch of engineering concerned with the application of physical mechanicsMachine, especially in opposition to an electronic itemMechanical watch, utilizing a non-electric mechanismMechanization, using machine labor instead of human or animal laborAutomation, using machine decisions and processing instead of humanManufactured or artificial, especially in opposition to a biological or natural component
Mechanical advantage (MA) is found by dividing the output force by the input force. It can also be calculated using the ratio of the distances moved by the input and output forces in some machines. For example, in a lever, MA is determined by the lengths of the effort arm and the load arm. A higher mechanical advantage indicates that less input force is required to lift a heavier load.
Some of the brands of mechanical pencils include, but are not limited to, Bic, Pentel, Zebra, uni-ball, Sharpie, and Pilot. It is interesting to note that mechanical pencils can be in the plain, graphite color or there can be colored graphite used in colored mechanical pencils.
Energy conversion I would say means converting say thermal energy to mechanical, or mechanical to electrical, or other conversions you can think of. Now some machines do this, like electrical generators, or electric motors which is the same but in reverse. Other machines are just mechanical, like a gearbox for example, mechanical energy in and mechanical energy out. So the word machine is more general, energy conversion devices are a sub-set of machines.
Tools: stethoscope, thermometer, some diagnostic tools and minor mechanical tools Machines: radiograph, anesthetic vaporizer, autoclave

Some examples of electromagnetic machines include electromagnets, electric motors, generators, transformers, and solenoids. These machines use the principles of electromagnetism to generate, transmit, and convert electrical energy into mechanical energy or vice versa.
Not all machines have motors. While many machines, especially those designed for mechanical work or movement, utilize motors to convert electrical energy into mechanical energy, there are machines that operate without motors, such as simple machines like levers, pulleys, or inclined planes.

She worked with Charles Babbage who had designed some mechanical machines. She was in effect writing programs in that she was manipulating symbols according to rules for a machines that Babbage was designing. She also foresaw the capability of computers to do more than calculations.
They can't uless some parts are hidden from inspection.
A compound machine consists of two or more simple machines put together. In fact, most machines are compound machines. Compound machines can do more difficult jobs than simple machines alone. Their mechanical advantage is far greater, too. Some examples are a pair of scissors and a bicycle.
Any factory that has machines or tooling that need to be made, needs mechanical engineers. Some companies always buy their equipment, but some companies like to make their own.
Babbage proposed his difference engine in 1822 and his analytical engine some years later. Both were mechanical computers (like old adding machines) Babbage built neither. It was not until recently (1991) that a working difference engine was completed.
Because some energy is expended in overcoming the friction and not applied to performing the task which the machine is meant to do.
Machines produce mechanical energy through the movement of their parts, and electrical energy when powered by electricity. Some machines also generate thermal energy through processes like combustion or friction. Overall, machines convert one form of energy into another to perform tasks.
