Here are my trashcan technical drawings.

calculation in LibreOffice calculation in FrameWork Here are my beam calculations. These calculations include: beam deflection moment of inertia around horizontal axis section modulus bending moment stress. The results allow to determine the strength and deflection of the beam.

Calculation in LibreOffice Computer calculation Here are my calculations in LibreOffice. The linked spreadsheet contains several sheets with different calculations. These calculations include: 1. Area of section 2. Distance of CG (Center of gravity) from lower edge 3. Moment of Inertia-horizontal axis 4. Moment of Inertia-vertical axis Moment of Inertia (of section) is a term used to describe the capacity of a cross-section to resist bending. A beam cross-section has a center of gravity and two principal axis. For symmetrical section (such as I-beam) principal axis are axis of symmetry. In a formula for beam deflection, the moment of inertia is part of a denominator. If the moment of inertia is increased, the deflection decreases.

Here is my beam calculation in FrameWork.

S1-M-030219-assembly cab_assembly Here are the models of cab_assembly and S1-M-030219-assembly.

Here is my beam deflection calculation in LibreOffice Calc using custom function. Using Macros, I created a function that calculates deflection for two types of beams: cantilever and simple. Here is the function: function DeflectionP(key,P,E,J,l,a,b) if key="simple" then DeflectionP=P*a^2*b^2/(3*E*J*l) if key="cantilever" then DeflectionP=P*l^3/(3*E*J) end function

Here are my drawings of 2nd cabinet. This cabinet was designed as improvement of Sheet Metal Cabinet 1.

Here is my parameterization of an I-beam with unequal flanges. 1) Create a simple I-beam with following dimensions tf=20 tw=10 w1=150 w2=350 h=500 L=1000 2) Go to "Dump Study" 3) Open the file and write new dimensions for the flange tf =10 tw =5 w1 =30 w2 =50 h =40 L =100 Box_1 = geompy.MakeBoxDXDYDZ( w1 , L , tf ) Box_2 = geompy.MakeBoxDXDYDZ( tf , L , h ) geompy.TranslateDXDYDZ(Box_2, w1 /2- tf /2, 0, tf ) Box_3 = geompy.MakeBoxDXDYDZ( w2 , L , tf ) geompy.TranslateDXDYDZ(Box_3, -10, 0, tf + h ) 4) Save and "Load Study" in Salome. Result: the flange will have different dimensions based on the values you entered in the script.

before after Here is how to change parameters of an object in Salome using Python program language. Create a simple object with specific dimensions Go to "Dump Study" and save in .py Open .py file and find the dimensions of the object. Create new dimensions for the object. (Example below:) r =5 h =120 r2 =46 h2 =112 Cylinder_2 = geompy.MakeCylinderRH( r, h ) Cylinder_1 = geompy.MakeCylinderRH( r2, h2 ) Create new file in Salome (geometry) and go to "Load Study". Result: the object should now have the new dimensions entered in Python.
