Nkọwa: k = mgbanwe na-agbanwe agbanwe, F = gwa, Δx = mmụba n'ogologo roba
Mgbanwe na-agbanwe agbanwe nke roba:
k_A = F / Δx = 1 / 0,05 = 20 N/m
k_B = F / Δx = 2 / 0,025 = 80 N/m
k_C = F / Δx = 1 / 0,025 = 40 N/m
k_D = F / Δx = 2 / 0,05 = 40 N/m
k_E = F / Δx = 2 / 0,25 = 8 N/m
Azịza ziri ezi bụ E.

Oge opupu ihe ubi na-agbanwe agbanwe:
k_A = 7/0,035 = 200 Nm^-1
k_B = 8/0,025 = 320 Nm^-1
k_C = 6/0,020 = 300 Nm^-1
k_D = 9/0,045 = 200 Nm^-1
k_E = 10/0,033 = 303 Nm^-1
Ihe kachasị na-agbanwe agbanwe bụ 320 Nm^-1.
