Answer :
Answer:
total elongation = 0.0125 in
Explanation:
given data
length = 25 in
tensile stress = 15,000 psi
to find out
total elongation of a steel bar
solution
we take here elasticity E = 30 × [tex]10^{6}[/tex] psi
so we get here total elongation of steel bar that is express as
total elongation = [tex]\frac{stress*length}{E}[/tex] ..........................1
put here value and we will get
total elongation = [tex]\frac{15000*25}{30*10^6}[/tex]
total elongation = 0.0125 in
