As shown below, a beam of length Lis in equilibrium while being fully submerged in water. The beam is horizontal and a vertical string is attached to ene end. The dot represents the center-of-mass and is 0.28BL from where the string is attached. The buoyant force acts on the geometric center of the beam. The tension in the string is 870 N. Determine the beam's weight & the buoyant force en the beam.
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.
