luas a=5cm2,luas b=10cm2,Fb=400N,ditanya=tekanan pada A adalah...N/cm²

P = F/A

Pa = Pb
Fa/LA = Fb/Lb
Fa/5 = 400/10
Fa = 40×5
Fa = 200 N

Pa = 200/5
Pa = 40 N/cm^2

atau bisa dgn cara

Pb = Fb/Lb
Pb = 400/10
Pb = 40

Pa = Pb
Pa = 40N/m^2

Dik: Aa= 5cm^2
Ab= 10 cm^2
Fb= 400 N
Dit:pa =...
Jawab:
Fa/Aa=Fb/Ab
Fa/5= 400/10
Fa=400/10×5
Fa=200N
Tekanan dia A= Fa/Aa
=200/5 =40...
Atau :
pa=pb
pa=Fb/Ab
pa=400/10
pa=40 N/cm
