Question

A wooden cylinder has the dimension: diameter, d = 40 cm and height, hcyl = 40 cm. The specific gravity of the wooden cylinder is 0.6. A copper disc, with a diameter of 40 cm and height, hcu = 1 cm, is rigidly attached to the bottom end of the wooden cylinder. The specific gravity of the copper disc is 8.8. The combination of the wooden cylinder and copper disc is placed in the water with their axis are in a vertical position.

(i) Calculate the height of the combined body, which is below the water surface.

(ii) If the height of the copper is to be changed, determine its minimum value so that the combined body is fully submerged.

Answer #1

A solid cylinder of diameter 3.4 m has a height of 2.6 m. Find
the distance from the center of buoyancy to the metacenter (in m)
of the cylinder when it is floating in water with its axis
vertical. The specific gravity of the cylinder is 0.5.

An aluminum cylinder has a diameter of 3 cm and height of 4 cm.
It is underwater but connected to a string that holds the cylinder
off the bottom of the container of water.
The cylinder is stationary. Calculate the tension in the string
in N.
The density of aluminum is 2.7x103 kg/m3,
and water is 1.0x103 kg/m3.

A 6.0-cm-diameter cylinder of nitrogen gas has a 4.0-cm-thick
movable copper piston. The cylinder is oriented vertically, as
shown in the figure, and the air above the piston is evacuated.
When the gas temperature is 15 ∘C , the piston floats 20cm above
the bottom of the cylinder.
A. What is the gas pressure?
B. How many gas molecules are in the cylinder?
C. Then 1.5 JJ of heat energy are transferred to the
gas. What is the new equilibrium temperature...
