For example, if a steel rod with an elastic modulus of 200 GPa and a length of 1 m is subjected to a tensile force of 10 kN, then the rod will stretch by 1.5915 mm. Additionally, a concrete beam ...

In this paper, we wish irradiate electron-beam to STC-5 that is used much as spiral spring's materials of industry application fields. The purpose is improving elastic force of STC-5 through ...

The apparatus that accelerates electrons which are emitted from an electron gun to produce a high energy electron-beam. The basis of electron beam technology is electric energy represented by ...
