Now, Miloš used the sum of vertical forces to find the remaining reaction. ∑Yi=0sum of cap Y sub i equals 0
: Kako nema horizontalnih spoljnih sila, statika zadaci za srednju skolu fixed
Since the phrase "statika zadaci za srednju skolu fixed" suggests you are looking for a review of a specific set of solved problems (likely a PDF or a study guide titled "Fixed" or "Riješeni zadaci" for high school statics), I have prepared a review based on the standard quality expectations for such educational materials in the region (Physics/Mechanics for high school). Now, Miloš used the sum of vertical forces
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) statika zadaci za srednju skolu fixed
: Proračun momenta sile za određenu tačku, što je ključno za postavljanje jednačina ravnoteže. 💡 Primer zadatka (Analitičko određivanje reakcija) Zadatak : Kugla težine oslonjena je na glatku strmu ravan pod uglom od 45∘45 raised to the composed with power i vezana užetom pod uglom od 30∘30 raised to the composed with power . Odrediti reakciju podloge NAcap N sub cap A i silu u užetu Postupak :
Uvek uradite proveru preko sume momenata za drugu tačku (npr. oslonac ).
