Wyjaśnienie:
[tex]S_1=2cm^2[/tex]
[tex]F_1=600N[/tex]
[tex]S_2=900cm^2[/tex]
[tex]szukane:F_2[/tex]
[tex]p_1=p_2[/tex]
[tex]\frac{F_1}{S_1}=\frac{F_2}{S_2}[/tex]
[tex]F_1*S_2=F_2*S_1/:S_1[/tex]
[tex]F_2=\frac{F_1*S_2}{S_1}[/tex]
[tex]F_2=\frac{600N*900cm^2}{2cm^2}=270000N=270kN[/tex]
[tex]dane:\\F_1 = 600 \ N\\S_1 = 2 \ cm^{2}\\S_2 = 900 \ cm^{2}\\szukane:\\F_2 = ?\\\\Rozwiazanie\\\\Z \ prawa \ Pascala\\\\\frac{F_1}{S_1} = \frac{F_2}{S_2}\\\\F_2\cdot S_1 = F_1\cdot S_2 \ \ /:S_1\\\\F_2 = F_1\cdot\frac{S_2}{S_1}\\\\F_2 = 600 \ N\cdot\frac{900 \ cm^{2}}{2 \ cm^{2}}\\\\F_2 = 270 \ 000 \ N = 270 \ kN[/tex]
