a tube is a concentric circle. Therefore, for a tube with inner and outer diameter ( d and D ) having thickness t , the area of cross-section can be written as:AC= π * (D2- d2) / 4.

Cross-sectional area for stress calculations I am having a lot of difficulty calculating the cross-sectional areas necessary for normal/shear stress problems. If the cross-section is a square or circle, I'm fine, but when the problem makes a diagonal section through the object I get really ...
Thermal conductivities of copper, brass and steel are 0.92,0.26 and 0.12 CGS units respectively. Rate of heat flow through copper rod is: View Solution Q5 Three rods of copper, brass and steel are welded together to form a Y - shaped structure. Area of cross - section of each ro...
If the cross section is parallel to the axis of symmetry, then the area of the cross section is simply a circle with an area of πr2. If the cutting plane is inserted at a different angle, the shape generated is an ellipse. The area uses the corresponding formula: πab (where a is...

With the development of the hypersonic weapon system, the non-circular cross-section projectile with more space utilization has attracted extensive attention. The high-velocity penetration mechanism of the non-circular cross-section projectile is a cruci
The area moment of inertia of a solid circular cross-section about its neutral axis isINA=πR44. The polar moment of inertia of a solid circular cross-section about its neutral axis isJNA=πR42. The centroid of a semi-circle is located at4R3...
The Type M specimen, when configured as an o-ring, circular band, or other irregular shape shall be at least 1.25 mm (0.05 in.) in cross-sectional diameter, unless it is known that results equivalent to the 1.25-mm (0.05-in.) values are obtained with a thinner specimen....
