    Pascals Law Problem

    1. The problem statement, all variables and given/known data

    You have a vehicle with four tires of 20 cm wide with 2 atm air pressure. Calculate
    contact area (cm^2) of each tire on the road. The gross vehicle weight is 1 tonne.

    2. Relevant equations


    3. The attempt at a solution


    therefore, A=(9.8x10^6)/200000=49m^2

    I am not sure if I am right so far,

    can u assist me if I am incorreect

    Re: Pascals Law Problem

    That's a lot of kilograms for a tonne! tonne = 103 kg.
    The method is okay for finding the total contact area. Just fix the tonne value.
