    Which Cart Sinks Less in Rainy Weather: Wide or Thin Wheels?

    hi, this is my question: A farmer has two carts. The carts have the same weight, but one has four narrow wheels and the other has four wide wheels. In rainy weather, which cart sinks less into soft ground, and why? would it be the wide wheels because the weight is spread?
