In designing a cylindrical pressure tank 1m in diameter, a factor of safety 2.5 is used. The cylinder is made of steel (oyield = 200MPa), and will contain pressure up to 7MPa. What is the required wall thickness based on circumferential stress condition?
1. The circular tube shown in Fig. 1 is subjected to a uniform internal pressure P; and external pressure Po. Using the Navier equations of equilibrium, i.e., a displacement formulation approach, determine the radial displacement component u, and the stress components o, and og0 in terms of P;, Po, r; and r̟. Hint: Use the Navier equations of elastostatics and cylindrical symmetry to reduce the 3-dimensional to a one-dimensional problem. E, v Po P

A silicon carbide ball with 5 mm in diameter has volume based CLTE (a,) of 8.1 x106/°C. If the ball is heated from 100 to 1750°F, calculate the increase in diameter. Convert first the temperature to °C. Note: (AV/V) = (V-V.)/Vo= av AT
When greater precision is required for pressure measurements, a device called micromanometer is used as shown in the figure. Suppose that an initial static equilibrium, the micromanometer has x = 1.22 m and y = 1.36 m. If the pressure at pt.

CORRECT ANSWER PLS
A steel sleeve of 150 mm outside diameter is to be shrunk on to a solid steel shaft of 100 mm diameter. If the shrinkage pressure set up is 15 MN/m², find the initial differencé between the in- side diameter of the sleeve and the outside diameter of the shaft. What percentage error would be involved if the shaft were as- sumed to be incompressible ? For steel, E = 208 GN/m², v = 0-3.

1. Most bridges contain interlocking steel grates (α steel = 1.2 x 10 - 5 ºC -1 ) that allow the bridge toexpand and contract with the changes in temperature. The Golden Gate Bridge in San Francisco isabout 1350 meters long.(A) The seasonal temperature variation in San Francisco ranges from about 0ºC to 30ºC. Howmuch will the bridge expand between these two extremes?(B) What percent of the length of a subcompact automobile, 2.5 meters, does this gaprepresent?2. Selena has a fire in her fireplace to warm her 20ºC apartment. She realizes that she hasaccidentally left the iron poker (α iron = 1.2 x 10 -5 ºC -1 ) in the fire. How hot is the fire if the 0.60-meter poker lengthens 0.30 cm?3. Just before midnight, when the air temperature of 10.0ºC, Karl stops and fills the 0.0600 m 3 gastank in his car. At noon the next day, when the temperature has risen to 32ºC, Karl finds a puddle ofgasoline (βgas = 3 x 10 -4 ºC -1 ) beneath his car.(A) How much gasoline spilled out of Karl's car?…
Problem 5 A square tube is open to air at atmospheric pressure on the top and capped with a porous membrane on the bottom. The tube cross section is L = 1 cm by L = 1 cm. The porous membrane contains 100 vertically oriented cylindrical pores of diameter d = 0.1 mm. Surface tension holds a column of water (o = 0.072 N/m) from falling through the membrane. The contact angle of water with the tube is 20°. The contact angle of water with the membrane pore walls is 180° (as shown) just before the water column spills through the membrane. The membrane is 0.01 mm thick, over which there is negligible hydrostatic pressure difference. a) Estimate the vertical capillary force by the tube on the water column. b) Estimate the vertical capillary force by a single membrane pore on the water column. c) Estimate the maximum water column height that the system can hold up.
