Homework Statement



length: 15 cm
Δlength ?
diameter 1.3 cm
pressure 17795 pa
γ= 2.0*10^11 Nm^2

Homework Equations



ΔL=γLA/F

The Attempt at a Solution



i could not find the answer don' know where to place pressure
 
Physics news on Phys.org
pressure = Force / Area

Do you have any study material from where you study ? :eek:
 
Your Young's modulus equations are not correct.
Young's modulus = stress/ strain
Stress = Force/area = F/A
Strain = extension/orig length strain = ΔL/L
Put these in the stress/strain equation and take it from there.
