Tensile Testing Machines. Tensile strength is the stress at which a material breaks or permanently deforms. There are three definitions of tensile strength, yield strength, ultimate strength and breaking strength. Tensile tests are usually carded out on wire, strip or machined samples with either circular or rectangular cross section. Test pieces are screwed into or gripped in jaws and stretched by moving the grips apart at a constant rate while measuring the load and the grip separation.
According to the Encyclopaedia Britannica, the Japanese currency is called the yen. The symbol of the yen is Â¥. The yen is among the major international currencies, due to Japan's economic renaissance in the second half of the 20th century.
The yen (en) was established as the official unit of currency in 1871. The name en was used because it means round, as opposed to the oblong shape of previous coinage. One hundredth of a yen is called a sen, although this unit is so small that it is only mentioned today in the financial markets. The Bank of Japan, established in 1882, issued its first bank notes in 1885.
