Basit Makineler
BASÄ°T MAKÄ°NELER
Üzerine uygulanan kuvvetin doğrultu , yön , şiddet ve uygulama noktasını değişikliğe uğratarak bir yük üzerindeki işin daha kolay yapılmasını sağlayan alete BASİT MAKİNE denir.

NOT: * Hiçbir basit makinede işten kazanç yoktur. Yükün yaptığı iş kuvvetin yaptığı işe eşittir.
*Kuvvetten ne kadar kazanç varsa yoldan da o kadar kayıp vardır.
