A trolley has a mass of 1200 kg and carries equipment with a mass of 350 kg. It rests on four identical feet, each with a contact area of 0.025 m2. The total force from the trolley and equipment acts normal to the floor. Gravitational field strength, g=9.8 N/kgg = 9.8\ \text{N/kg}g=9.8 N/kg.
Calculate the pressure the trolley and equipment exert on the floor.
