Muai panjang

Rumus:
\!L_{t}=\!L_{0}(\!1+\alpha\times\Delta t)
  • \!L_{t} = panjang akhir (m, cm)
  • \!L_{0} = panjang awal (m, cm)
  • \alpha = koefisien muai panjang (/°C)
  • \Delta t = perbedaan suhu (°C)

Muai volume

Rumus:
\!V_{t}=\!V_{0}(\!1+\gamma\times\Delta\!t)
Keterangan:
  • \!V_{t} = volume akhir (m3, cm3)
  • \!V_{0} = volume awal (m3, cm3)
  • \gamma = \!3\alpha = koefisien muai volume (/°C)
  • \Delta t = selisih suhu (°C)

Muai luas

Rumus:
\!A_{t}=\!A_{0}(\!1+\beta\times\Delta t)
Keterangan:
  • \!A_{t} = luas akhir (m2, cm2)
  • \!A_{0} = luas awal (m2, cm2)
  • \beta = \!2\alpha = koefisien muai luas (/°C)
  • \Delta t = selisih suhu (°C)
