Straight wooden stick has mass M=0.40kg, Length L=1.2m, uniform cross-section A=18cm2, and constant density has a small mass m=0.20kg attached to its one end. The stick is partially submerged in water (density =1,010kg/m³). While in equilibrium, the stick will float in a vertical position with large part of it submerged. The stick is then pushed down by distance ymax =50cm from the equilibrium, and released. Find the period of the oscillations of this system. State your answer to the nearest 0.01s. Assume no drag forces are acting in this situation. Take g=9.8m/s2
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.
