At point B, she drew the 200 N weight pointing straight down.
Za rešavanje zadataka iz statike sa fiksnim osloncima (uklještenjem), uvek koristite tri jednačine ravnoteže: statika zadaci za srednju skolu fixed
At point A (left support):
450 N(RA)+150 N(RB)=600 N(F)450 N open paren cap R sub cap A close paren plus 150 N open paren cap R sub cap B close paren equals 600 N open paren cap F close paren The beam was perfectly balanced. Final Answer The reaction forces at the supports are: At point B (right support): Because the heavy bag was closer to pedestal Statics Problems for High School: A Focus on
sum of cap M sub cap A equals 0 ⟹ cap F center dot the fraction with numerator cap L and denominator 2 end-fraction minus cap F sub cap B center dot cap L equals 0 2. Izračunavanje reakcije cap F sub cap B Iz gornje jednačine izolujemo cap F sub cap B sum of cap M sub cap A equals
- From horizontal: (T_1 \cdot 0.866 = T_2 \cdot 0.5 \Rightarrow T_2 = 1.732 T_1).
- Substitute into vertical:
(T_1 \cdot 0.5 + (1.732 T_1) \cdot 0.866 = 98)
(0.5 T_1 + 1.5 T_1 = 2 T_1 = 98 \Rightarrow T_1 = 49 ,\textN), then (T_2 = 84.9 ,\textN).
