4.1 Defirmation Of Solids Flashcards
1
Q
Hookes law
A
The extension of a spring (x) is directly proportional to the force applied to it, provided the limit of proportionality is not exceeded
2
Q
Stress
A
The applied force per unit area of cross section
3
Q
Ultimate tensile stress ( UTS )
A
The maximum stretching force per unit area without the material breaking
4
Q
Strain
A
The ratio of the change in length of a specimen to its original length
5
Q
Young’s modulus ( E )
A
A measure of the stiffness of a material, determined by the ratio of stress ➗ strain
