Such allowable stresses are also known as " design stresses " or " working stresses ."
2.
While most structures were designed to be temporary, wartime working stresses were adopted at least 33 % greater than normal working stresses.

For elements in traction, a reduction of 25 % in the working stress or an increase of 25 % in the volume is therefore also necessary in the majority of cases.

*It is not always straightforward to establish the nature and the overall maximum intensity of the forces " F " ( including dead weight ) to which the structure is subject, which again has a direct influence on the working stress.
6.
For example, if the cable has a working stress of 50 GPa and a Young's modulus of 1000 GPa, its strain will be 0.05 and its stored elastic energy will be 1 / 2 & times; 0.05 & times; 50 GPa = 1.25 & times; 10 9 joules per cubic meter.
