Question

F=60N,bR=50cm,bF=1m ,aflati R plizz

Answer 1

$F=60 \ N \\ b_F=1 \ m \\ b_R=50 \ cm=0,5 \ m \\ \boxed{R-?} \\ \bold{Rezolvare:} \\ \boxed{F \cdot b_F=R \cdot b_R} \\ \Rightarrow R= \frac{F \cdot b_F}{b_R} \\ R= \frac{60 \ N \cdot1 \ m}{0,5 \ m} = \frac{60 \ J}{0,5 \ m} \\ \Rightarrow \boxed{R=120 \ N}$
