Re-design the structure in Example 1 avoiding thick clusters of plies and taking into account in-situ strength. Use tt = 1.2 mm and ν23 = 0.38.
Example 1
Design a cylindrical pressure vessel with diameter d = 4 m, internal pressure p = 3.0 MP a, with a COV Cp = 0.10 to achieve a reliability Re = 0.95 with respect to the burst pressure. Use a coordinate system on the surface of the cylinder with the y-axis oriented in the hoop direction and the x-axis oriented along the length.
Assume that the strength reported in Figures 1- 2 has a variability represented by COV CF = 0.12.
Find what are the elements present in sulphur and mention its advantages and disadvantages
A daring ranch hand sitting on a tree limb wishes to drop vertically onto a horse galloping under the tree. The constant speed of the horse is 12.0 m/s, and the distance from the limb to the level of the saddle is 4.00 m.
With what speed in miles/hr (1 m/s = 2.23 mi/hr) must an object be thrown to reach a height of 91.5 m (equivalent to one football field)? Assume negligible air resistance.
A 839-N man stands in the middle of a frozen pond of radius 6.0 m. He is unable to get to the other side because of a lack of friction between his shoes and the ice. How long does it take him to reach the south shore
A standard 100 W (120 V) lightbulb contains a 7.70cm-long tungsten filament. What is the diameter of the filament
A raft of mass M with a man of mass m aboard stays motionless on the surface of a lake. Determine the displacement of the raft relative to the shore
The greatest height reported for a jump into an airbag is 99.4 m by stuntman Dan Koko. In 1948 he jumped from rest from the top of the Vegas World Hotel and Casino. He struck the airbag at a speed of 39 m/s (88 mi/h).
Some planetary scientists have suggested that the planet mars has an electric somewhat similar to that of the earth, producing a net electric flux of 3.63X10^16 N*m/C at the planet's surface.
A 0.25 kg harmonic oscillator has a total oscillation energy of 9.9 J. If the oscillation amplitude is 20.0 cm, what is the oscillation frequency
How much energy is transferred to the oxygen as heat? What fraction of the heat is used to raise the internal energy of the oxygen?
