Rumus-Rumus Fisika Lengkap/Pemuaian

Muai panjang

Rumus:

${\displaystyle \!L_{t}=\!L_{0}(\!1+\alpha \times \Delta t)}$

• ${\displaystyle \!L_{t}}$ = panjang akhir (m, cm)
• ${\displaystyle \!L_{0}}$ = panjang awal (m, cm)
• ${\displaystyle \alpha }$ = koefisien muai panjang (/°C)
• ${\displaystyle \Delta t}$ = perbedaan suhu (°C)

Muai volume

Rumus:

${\displaystyle \!V_{t}=\!V_{0}(\!1+\gamma \times \Delta \!t)}$

Keterangan:

• ${\displaystyle \!V_{t}}$ = volume akhir (m³, cm³)
• ${\displaystyle \!V_{0}}$ = volume awal (m³, cm³)
• ${\displaystyle \gamma }$ = ${\displaystyle \!3\alpha }$ = koefisien muai volume (/°C)
• ${\displaystyle \Delta t}$ = selisih suhu (°C)

Muai luas

Rumus:

${\displaystyle \!A_{t}=\!A_{0}(\!1+\beta \times \Delta t)}$

Keterangan:

• ${\displaystyle \!A_{t}}$ = luas akhir (m², cm²)
• ${\displaystyle \!A_{0}}$ = luas awal (m², cm²)
• ${\displaystyle \beta }$ = ${\displaystyle \!2\alpha }$ = koefisien muai luas (/°C)
• ${\displaystyle \Delta t}$ = selisih suhu (°C)
