Diketahui:
h=5 meter
A=8+5=13 m²
m=30 Ton=30.000 kg
E=20x10⁹N/m²
g=10 m/s²

ditanya=
a) σ=
b) ε=
c) ∆h=
jawab:
★Tegangan Tiang(σ)
σ = F/A
σ= m×g/A
σ= (30.000 x 10)/13
σ=300.000/13
σ= 23,07 N/m²
★Regangan Tiang (ε)
ε=σ/E
ε=23,07 /20x10⁹N/m²
ε=1,15×10^-⁹N/m²
★Perubahan ketinggian Tiang (∆h)
∆h=ε×h
∆h=1,15×10^-⁹N/m² ×5 meter
∆h=1,15×10=11,5×5
∆h=57,5×10^-⁸ m
