If the cross section of metal in the projection is fractured, the heat build up will form more rapidly in the stretched material then at the workpiece interface area. This will result in the projection collapsing before fusion takes place.
  If I remember right... the very first video game was: PONG. It came out in the early to mid-70's, somewhere between 1972-1974. After that came ATARI. I know I'm right ab â¦ out the name (PONG)... the year; not so much.
The earliest video game (or rather, interactive electronic game)  was a missile simulator created on a cathode-ray tube in 1947. The  first home console was the Magnavox Odyâ¦ssey, the production of  which started in 1966. It was released in its final form in 1972.   That would depend on your definition of the console. WAaaaaaay back  in the late 70s there were PONG type games that were the first.  These gaming devices hooked up to your TV's Ariel antenna input and  just had two dial type controllers on a little box.   But, the first gaming console that I remember having a large  library of cartridge games was the ATARI 2600.
