Dear All, Please see the picture. I need to find the bending stress for that profile. Its hollow tube dia= 38 mm, 4 mm thick. its is acted with udl of 500 N/m2 on its outer surface. How can I estimate the bending stress, deformation. Assume it as mild steel with E = 200 Gpa, poission...

Please put some more materials for standard rectangular tank design ,, Thanks in advance.

Hi Tyroman, Thanks for the reply. 1 )I am planned to place my tank on a flat surface where the atmosphere pressure won't comes into play on the bottom plate. So i need apply the atm pressure+hydrostatic pressure inside the tank for the stress calculations. 2) And please let me know...

Hi Cyrus, Thanks for the reply. 1) So you mean that the 0.2 bar is wrong answer?? 2) then we need to take atmospheric + hydrostatic pressure for stress calculations.

Dear guys, I got a common doubt regarding the pressure at the bottom of a open tank filled with water. 1) Assume a tank of 2m height, filled with water. So the hydrostatic pressure at the bottom of the tank will be 0.2 bar(rho*g*h). Wondering! it is less then atmospheric pressure(1 bar)...

:biggrin: thanks i solved it...

hi, Is there any way, to find a point whether it lies inside a irregular cube. other than finding volume. where cube can be rotated in any direction.

hey thanks... got it...

from this t(a,b,c) + (1-t)(d,e,f)=(x,y,z), the unknown t will be a vector.which i gave the as (u,v,w). could you come some more detail please..

hi dick & clustro 1) I think from the attached figure you will be able to get my question. 2) the red lines in one cube will cut the outer surface of other cube. I need to find the location where the edge(red line) cuts the outer face.(six points will occur! am i rite). Is there any...

more clear please. any one.

hi shredder, I got ur answer, please check whether i am correct. (x,y,z) is new point where need to find it is in that path. t(a,b,c) + (1-t)(d,e,f)=(x,y,z) from this i can get the t, assume my t as t(u,v,w). so these u , v and w should be inbetween 0 and 1,so that t lies in the...

Imagine there are 2 cubes of same finite dimension. Example from 0 to 1 in all three axis. place the first cube with the origin (0,0,0), and place the second cube with the origin (0.5,0.5,0.5). So now both the cubes will get intersected with each other. I need to get the points where the edges...

hi I know two points in 3d space.I know another point in the space and need to know whether that point lie in between the two points(i.e same line). can anyone give me simple algorithm other than logic. Thanks in advance.

hey thanks for your quick reply. I mean two cubes are placed one over another, an we need to find the points of intersection. the algorithm i need is, it should be able to get the intersection points though my cubes are rotated in any direction. I will use it for unstructured 3d cartesian mesh...
