Basic Terminologies
Terminology is a systematic study for the implementation of the terms or words and their correspondence within their respective domain of human activity in the case of multilingual (more than 2) or bilingual (2) languages. Terminology is defined as the study of concepts, conceptual related phrases or expressions, and lexicography, on the other hand, is the discipline used to study any type of word and its meaning. Technical ventures and institutes create and gather their resources or word collection also known as a Glossary.
Common Units Of Pressure
Pressure is something that we experience in daily life but fail to recognize it as our body is so accustomed to it. For example, the atmospheric air applies pressure on our body, but we don’t feel it as we are exposed to it since birth and our body is habitual to it. When we write using a pen, we need to apply some pressure over the pen to make it start writing. But these are our day-to-day activity which we fail to recognize
Calculate the characteristic dimension of the cross-section, b, and paste the section into the form, including dimensions in [cm]. Calculations of the cross-section characteristic dimension b, and other calculations should be attached to this solution.
2. According to the instructions in the form, do the calculations in units [kN] and [cm],e.g. moments of inertia in [cm4],stress in [kN/m2]. Recalculate stress into [MPa].
A. For the structure shown:1.Determine the number of static unknowns and number of equations of equilibrium. 2.Find the reactions at supports and at hinge connections, draw FBD with depicted calculated reactions for eachframe elements separated(F1).3.Determine the functions and draw the diagrams of shear force, axial force and bending moment along the frame elements (F2-F4).Check the balance of forces and moments exerted on the node B (F5, F6). Determine the most strained section (section at which the internal forces take its maximum values).B.For the cross-section shown: 1.Find and mark Centroid. Determine the moments of inertia about the horizontal and verticalaxes through Centroid and about axes rotated byangle. Find principal moments of inertia, find and draw principal axes throughCentroid. Create the Mohr circle with depicted principal moments of inertia and moments calculated for angle (F7). On the cross-sectional sketch draw axes through Centroid rotated by α.2.Assuming magnitudes of internal forces that occur at the most strained section, determine dimensionbof the cross-section, assuming that it is made of steel of yield limit Rpland safety coefficient n. Draw asketch of the cross-section with markeddimensions (F8). Rpl= n= 3.For the obtained dimensions of teh cross-section,determine the functions and draw the diagrams of normal stress bσ(bending) and tσ(tension/compression) and resultant stress tbσσσmaxat the most strained cross-section (F9-F11). 4.Determine the functions and draw the diagrams of shear stress atthe most strained cross-section of the frame (F12).Determine the reducedstress due to Huber-Mieses-Hencky hypothesis atthe centroid. The project should contain 12Figures (F1-F12), the figures should be numbered and captioned.The cross-sectional characteristics shouldbe written in the Table.
