Overview
Statics is often the first major hurdle in high school physics where mathematics and the physical world collide in a rigorous way. A typical "Statika zadaci" (Statics problems) collection for high school aims to bridge the gap between theoretical definitions (Newton’s Laws) and practical application (force decomposition, torque, equilibrium). The quality of these materials is usually defined by how well they handle the transition from simple 1D problems to complex 2D moment calculations.
Equations:
(\sum F_y = 0 \Rightarrow R_Ay - 1000 = 0 \Rightarrow R_Ay=1000\ \textN upward)
(\sum M_A = 0 \Rightarrow M_A - (1000 \cdot 2.5) = 0 \Rightarrow M_A = 2500\ \textNm CCW)
- DST: U tački A – Ax (horizontalna, ovdje 0), Ay (vertikalna), M_A (moment uklještenja). U tački B – F = 500 N dolje.
- ΣFx = 0 → Ax = 0
- ΣFy = 0 → Ay – 500 = 0 → Ay = 500 N (gore)
- ΣM/A = 0 → M_A – (500 N * 4 m) = 0 → M_A = 2000 Nm (suprotno od kazaljke na satu)
- Odgovor: Ay = 500 N, M_A = 2000 Nm.
