Vídeo de preguntas y respuestas
What is the purpose of the tensile test?
The tensile test measures how much a material can stretch or deform under tension.
What is gauge length in tensile testing?
Gauge length is the length of the sample used for measuring elongation during the tensile test.
How is the diameter of the sample measured?
The diameter is measured at three different points, and the smallest value is used for calculations.
What components make up a tensile specimen?
Key components of a tensile specimen include grips, fillet, gauge section, and diameter.
What equipment is used for tensile testing?
A tensile testing machine is used, which includes grips, load cell, and control buttons.
How is the gauge length determined for a specimen?
The gauge length is typically set at four times the diameter of the specimen.
What measurements are taken after the tensile test?
After testing, the final length and diameter of the specimen are measured.
