30. A ship is towed into a port by two tugs, each of which is pulling the ship by a steel cable. The angle between the two cables is 60° and tension in each of them is 8.00 x 10 N. If the motions of ship is resisted by a viscous drag force of 5.856 x 10°N then the resultant force on it is: 1.386 x 10 N at an angle of 60° to one of the cables B A 2.144 x 10' N at an angle of 30° to one of the cables. 8.00 x 10' N at an angle of 30° to one of the cables 5.856 x 10' N at an angle of 30° to one of the cables D
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.
