The concept of the moment of inertia is pretty simple, although it looks like intimidating. It is just an angular form of mass that constitutes the relationship between torque and angular acceleration in a rotating system.
Just like F=ma of Newton's Second Law, torque is determined by the multiplication of angular mass (moment of inertia) and angular acceleration. So it is to understand how much torque is required to get a certain amount of angular acceleration or vice versa.
Different geometric shapes have their own moments of inertia in terms of their masses and areas which can easily be found on any textbook or internet.
Here it is examined to how to obtain the moment of inertia at a H-shaped beam, which is held together by three rectangulars named flanges and web.
Structural profiles like beams have their standards. To illustrate it can be checked on internet as npi, npi, ipe or heb which is used on example here. (Heb 100)
To find the moment of inertia on a beam, it is necessary to find the centroid of the beam firstly. Then area moments of inertia of flanges and web can be calculated regarding centroid.
As mentioned before, most of beams have their own standards and do not require a calculation of moment of inertia or any other properties. .
DAY [ 23 /100 ]
So the Past week , I was checking my YouTube account , and found that no stuff was provided by me from past few weeks.
So today , I utilised my Sunday to create one Video.
Its about CSS. .
You guys can Check it . [LINK IN BIO ]...suggestions are always welcome.😊
Now I am Going For A Walk .
What you guys have done today, on Sunday ??
I have planned next few hours for some Problem Solving Questions, after the Walk.
