A = 5 x 3 = 15 cm^2 = 15 x 10^-4 m^2
Dit : P ?
Jwb = P = W/A
= 3600 / 15 x 10^-4
= 360 x 10 / 15 x 10^-4
= 24 x 10^5
= 2,4 x 10^6 Pa
= 2,4 MPa
= 15 cm²
= 15 x 10⁻⁴
Area terkecil adalah 4cm dan 3 cm
A = 4 cm x 3 cm
= 12 cm
= 12 x 10⁻⁴ m²
F = 3600 N
P = F / A
= 3600 N / 12 x 10⁻⁴
= 3.000.000 Pa
= 3 MPa
maksimum 3 MPa karena semakin kecil areal semakin besar tekanan dengan gaya yang sama <C>
