PENYELESAIAN DINAMIKA PESAWAT ATWOOD DENGAN PERSAMAAN EULAR-LAGRANGE SEBAGAI ALTERNATIF PERSAMAAN NEWTON PADA FISIKA SMA

Melly Ariska

Abstract


Telah diturunkan persamaan gerak pesawat Atwood dengan persamaan Lagrange.  sistem mekanik dengan kendala holonomik untuk pesawat Atwood yang bergerak dapat digambarkan dengan persamaan Eular-Lagrange, yaitu sistem dinamika yang dapat digambarkan dengan persamaan diferensial dan energi sistem dinyatakan dengan jelas.  Persamaan pesawat Atwood yang dicari dengan Hukum Newton hasilnya sama jika dicari dengan menggunakan persamaan Eular-Lagrange. Persamaan Eular-Lagrange dapat merumuskan persamaan dinamika sistem yang lebih kompleks dengan jelas tanpa harus menginventarisasi gaya-gaya pada sistem gerak tersebut.

 


Keywords
