1. 1. Consider the figure below: A parabolic cylinder having a length
of 4m perpendicular to the paper submerged in water.
Compute for the resultant force on the surface OA.
2. A 40 mm diameter steel ball is used to cover a 16 mm diameter
hole in a pressurized chamber. If the weight of the ball is 78
kN/m3
and pressure of the gas inside the chamber is 30,000
kPa, compute for the total force needed to push the ball up into
the pressurized chamber.
3. A spherical metal is placed in a container which holds two
layers of different liquids, as shown below. One fluid has a
specific gravity of 1.25 and 240 mm in depth, and the other
fluids is 1.60 with a depth of 280 mm. The sphere has a
diameter of 220 mm and specific gravity of 7.5 is submerged in
such a way that half of the sphere is aligned with the
intermediate of the two fluids. Find the tension in the wire to
hold the sphere in its position.
