physik mathe aufgabe Fe,o,d/(11cm)^2 × 1/0,202 = 9,819 N/mm^2

Question

Fe,o,d/(11cm)^2 × 1/0,202 = 9,819 N/mm^2 

Gesucht: Fe,o,d in KN/cm^2

Answer 1

9.819 N/(mm^2) = 981.9 N/(cm^2) = 0.9819 kN/(cm^2)

Answer 2

Hallo,

sei  x = Fe,o,d  

x / (11cm)² • 1/0,202  =  9,819 N/mm²    | * 0,202 | * (11 cm)²

x  =   9,819 N/(1 mm)²  * 0,202 * (11 cm)²

     1 mm² = 0,01 cm²  ;   1 N = 0,001 kN

x  =  0,009819 kN / (0,01 cm²) * 0,202 * 121 cm²

x  ≈  24 kN/cm²
