2. A car tire makes contact with the ground in the shape of a rectangle, 10 cm by 10 cm. If the car's mass is 2000 kg, what pressure does the car exert on the ground as it rests on all four tires? (Remember a car has 4 tires) a) 1* determine the total area of the cars tire (Lx W x 4) b) convert that to m? c) Calculate the weight of the car. (Weight is a force) d) Find the pressure.
Fluid Pressure
The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.
Gauge Pressure
Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem to bother anyone as the bodily fluids are constantly pushing outwards with the same force but if one swims down into the ocean a few feet below the surface one can notice the difference, there is increased pressure on the eardrum, this is due to an increase in hydrostatic pressure.
