Teng massali 3 ta brusokning 3 xil holati rasmda tasvirlangan. Qaysi holatda sistemaning potensial…

Brusok o‘lchamlari $2a\times a$. Og‘irlik markazlari balandliklari yig‘indisi: 1-holat: $0{,}5a+2a+3{,}5a=6a$; 2-holat: $0{,}5a+1{,}5a+3a=5a$; 3-holat: $a+2{,}5a+3{,}5a=7a$. Potensial energiya $mg\sum h$ 2-holatda eng kichik.
