Kerakli asboblar: ikkita stakan, margansovka kristallari. Ishni bajarish tartibi

Kerakli asboblar: 1) Laboratoriya richag-chizg‘ichi; 2) Yuklar to‘plami; 3) Shtativ.
Ishning bajarilishi:
Shtativga laboratoriya richag-chizg‘ichi 58-rasmda ko‘rsatilganidek osiladi. Richagning chap tomoniga aylanish o‘qidan 10 sm uzoqlikda ikkita bir xil yuk osiladi. Richagning o‘ng tomoniga aylanish o‘qidan 20 sm uzoqlikda chap tomondagidek bitta yuk osiladi. Bunda richagning muvozanatda qolishi kuzatiladi. Shunga o‘xshash chap va o‘ng tomonlarga birinchi tajribada ko‘rsatilganidek ularga karrali yuklar osilganda richagning muvozanatda qolishi namoyish qilinadi. Tajribalarga ko‘ra richagning muvozanatda bo‘lish sharti keltirib chiqariladi:
