Card 1 of 20
Define extension xxx in terms of length.
A
x=original length−final lengthx = \text{original length} - \text{final length}x=original length−final length
B
Tensile stress is defined by the equation σ=FA\sigma = \frac{F}{A}σ=AF and is measured in pascals (Pa).
C
x=final lengthoriginal lengthx = \frac{\text{final length}}{\text{original length}}x=original lengthfinal length
D
x=final length−original lengthx = \text{final length} - \text{original length}x=final length−original length
