A woman of m= 63 kg stands on the ice. The contact area between her skate and the ice is A = 0.0065 m2 a) express the force that the person exerts on the ice, F, in terms of m and g. you do not need to include the force of the column air above her b) calculate the numerical value of F in N c) express the pressure on the ice from the person P in terms of F and A d) calculate tthe numerical value of P in Pa.
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.
