T= Total Tension From the diagram shown in FIG. B, each object has a Base Area of 100cm? and a vertical height of 10cm. They are connected with a strong tension wire of negligible weight at an equal distance of 20cm. They are all submerged in Water. Calculate the minimum Force (T) needed to start lifting all the connected objects. Given Data: Solid Gold Cone 10 cm 20 cm cSolid Aluminum Cylinder 10 cm for Solid Conical Gold: Density = 19,300 kg/m for Solid Aluminum Cylinder: 20 cm Solid Lead Cube Density = 2,700 kg/m3 10 cm for Solid Lead Cube: Density = 11,300 kg/m³ FIG. B Water Density = 1,000 kg/m³ %3D
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.
