When the first humans made ​​their first tools.
Because his wife made him sleep on the couch.
Mechanical model is a short or big model of prototype(e.g. Machine, machine parts)
Chair with mechanical curves on arms, square tapered legs, high square back made during the reign of Louis XIV of France.
The person is using mechanical energy to lift the chair. Mechanical energy involves the kinetic energy of moving the chair and the potential energy stored in the chair due to its position relative to the ground.
Charles Babbage is considered the father of the computer. He created the first mechanical prototype in the early 19th century.
We made a prototype of the rocket before we built it.
1 purpose of a prototype is to find design flaws. If any were made, another prototype might be made. If not, the next step would be manufacturing.
When a person lifts a chair, they are expending mechanical energy to overcome the gravitational force acting on the chair. This mechanical energy is transferred from the person's muscles to the chair, allowing it to be lifted. Additionally, there may also be some heat energy generated due to friction between the person's hands and the chair.
In Prototyping model instead of the end product a prototype is made. Advantage of prototype is that it helps in gathering and refining of requirements.
About 15% of cars are made by rapid prototype machines. You can read more about it en.wikipedia.org/wiki/Rapid_prototyping
When a person lifts a chair, they use mechanical energy from their muscles that is converted into potential energy as the chair is raised against gravity. The person's muscles do work on the chair to overcome gravity, increasing the chair's potential energy.
by having a brain and building it.
