Leonardo designed various machines, including mechanical devices like a war machine called the “armored car.” This invention is considered one of the earliest designs for a rolling combat vehicle. Who invented

For example, one target will activate mechanical “wind breaks” (gates) that will close off the sides of the game making it easier by eliminating the side drains. These “wind breaks” in reality would be the planting of lines of trees to lessen the impact of heavy wind. The key feature...
mechanical, and electric processes; and it is indeed likely that many lines of improvement have already been compelled to yield their utmost, reaching terminal forms. A moment’s thought will show that one main object must be the elimination of certain steps in the transfer of the energy; and...
Some clever inventions are stunning in their simplicity. A great example is the pneumatic Test-BallR Plug developed in 1952 by Lloyd Cherne. He was on a job in northern Michigan when, much to his dismay, the cast iron mechanical plug he was using (the only plug available at that time) ...
As a trained electrical and mechanical engineer, Tesla invented so many modern marvels, that he has shaped the world perhaps more than any other inventor. His discovery of the rotating magnetic field led to him devising a better system for electrical transmission, theAC (alternating current) syst...

Flow process chart was made by scientist Frank Gilbreth in 1921 as a presentation to American Society of Mechanical Engineers (ASME). A flow process chart is a diagram that depicts the step-by-step working of a program. Flow process chart was further developed by Allan H. Mogensen. ...
Engine and Mechanical Systems The Mark I was powered by aDaimler 6-cylinder petrol engineproducing 105 horsepower. This engine enabled the tank to reach up to 3.7 mph on rough terrain, typical for World War 1 tanks. The transmission system required a crew member to steer using a combination ...
IBM, for example, grew out of an earlier company selling intricate mechanical census-counting machines developed by Herman Hollerith; Sony made its name selling cheap, high-quality radios made with tiny transistors; Goodyear owes its name (and its chief product) to Charles Goodyear, a hapless ...
