Question

Airport Authority of India made a runway which can sustain a pressure of 2500 Pascal now read the following data
Mass of plane - 7200 kg.
Area of a tyre - 8

${m}^{2}$
​

Answer 1

Explanation: the pressure applied here is less than 2500 as we know the pressure is equal to force / area and by that the pressure here seems to be 9000 N/m2  but dont forget that the plane dont run on a single tire so the mass is equally distributed among 3 or 4 tiers and hence the pressure is less

hope it helps...... ; )
