Gdy stoisz na dwóch nogach
F=500N
S1=0.033 (jednego buta)
m = 50 kg
S₁ = 27,5 cm × 12 cm = 330 cm² = 0,033 m²
S₂ = 2S₁ = 2 × 0,033 m² = 0,066 m²
g = 10 n/kg
p₁, p₂ = ?
p = F/S
F = m × g = 50 kg · 10 N/kg = 500 N
p₁ = F/S₁ = 500 N/ 0,033 m² = 15 152 Pa = 15,152 kPa
p₂ = F/S₂ = 500 N/0,066 m² = 7 576 Pa = 7,576 kPa
(1 kPa = 1000 Pa)
