Calculating support forces on each tire

  1. Feb 17, 2010 #1
    1. The problem statement, all variables and given/known data

    Two uniform crates of 350kg are placed in the bed of a stationary 1500kg truck. Determine the support forces at each of the wheels

    The demensions are only around the horizontal axis

    2. Relevant equations
    Fx = n1 + n2 -M1g -m2g-m3g

    T= Dmg


    3. The attempt at a solution

    Thats about where I am at, Im just looking for a hint,

    Add mass of crates and truck -> find gravitational force -> divide by 4 (force is split over 4 tires)

    If it was uniform that would be right but its not uniform. This is what I came up with:

    Find center of gravity, Calculate torque, using that the sum of all forces has to equal total mass it should cancel out, any thoughts?
