Michael Mosley, Cassie Newland and Mark Miodownik from the BBC series 'The Genius of Invention' describe the scientific achievements of Nicklaus Otto, Karl Benz and Henry Ford. Prior to this, the steam locomotive had started a revolution. Richard Trevithickâs design had a boiler but this was removed to make the internal combustion engine. The German inventor Nicklaus Otto developed the first four-stroke engine in 1876. This could not be developed until kerosene, diesel and petrol were used in place of coal. Karl Benz then developed the worldâs first car using Ottoâs design.
A welding arc stabilizer including a source of high voltage and a switch for switching the source of high voltage across the electrode and the workpiece in the event the arc rectifies. The high voltage is switched across the electrodes within the completion of the half cycle in which rectification occurred.
The stabilizers' job is to provide stability for the aircraft, to keep it flying straight. The vertical stabilizer keeps the nose of the plane from swinging from side to side, which is called yaw. The horizontal stabilizer prevents an up-and-down motion of the nose, which is called pitch.
