Materials Flashcards
1
Q
Tensile stress
A
Tensile stress = Force / Area.
Measured in pascals (1Pa = 1 N m ^-2)
2
Q
Tensile strain
A
Tensile strain = Extension / Length
Strain is a ratio and therefore has no unit
3
Q
What does Young’s modulus show
A
Stiffness of a material
4
Q
What does tensile stress show
A
Strength of a material
