The man pushes the lawn mower at a steady speed with a force P which is parallel to the incline. The mass of the mower with attached grass bag is 50 kg with mass center at G. If θ = 15o , determine the normal forces NB and Nc under each pair of wheels B and C. Neglect friction. Compare with normal forces for the conditions of θ = 0o and P = 0.
