Rasmdan foydalanib K jismning massasini (g) toping. Bunda osma tarozining siljuvchi toshining massasi 2 kg.

Har yelka 10 bo‘lakdan iborat; L tosh 1-holatda tayanchdan 3 bo‘lak, 2-holatda 9 bo‘lak o‘ngda turibdi. Momentlar qoidasi: 1-holat: $10(m_X+m_K)=10m_Y+2\cdot 3$; 2-holat: $10(m_Y+2m_K)=10m_X+2\cdot 9$. Tenglamalarni qo‘shsak: $30m_K=24$, $m_K=0{,}8$ kg $=800$ g.
