23. Kubva pakuedza kuona kusimba kwerabha uchishandisa rabha yematayi, data rakawanikwa riri patafura inotevera. Zvinogona kugumiswa kuti kukosha kukuru kwerabha ndiko kuedza….
Kukurukurirana
Fomura yemutemo waHooke:
k = F / Δx
Chirimo chinogara chiripo:
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
Chinochinjika chikuru che elastic i320 Nm^-1.
Mhinduro chaiyo ndeiyi B.
