Why hollow semi spherical shape is present underneath the beverage can bottles ?


look at the above image, this semi-spherical shape we are talking about, in this question.
We try to find some reason behind it.

1)Standing stability from a structural point of view.
 
**in both case of MOI 1/2 is multiplied

in this above fig we have compared both the probable cases, As a result, we got "second can" have more mass moment of inertia means more force required to tilt, or we can say have more stability at standing position. That's why we prefered the second case over the first one.

2) Standing stability at the rough surface.

here provided video clip is enough to understand...

  1. Is this similar to the case of humans having flat feet are more likely to slip than humans having curvature in their feet?

    1. In case of human , curvature is reason of stiffness,,more stiffness means more control over the leg.

  2. But flat feets has a relation to friction with the surface so I am asking does the concept of MI also applicable on feets

  3. Can't we relate it to P=F/A..coz force is same in both the cases ,
    the one less area of contact will be pressing the surface more and will be required more force therefore to tip it off..

How to make dice game by using LabVIEW?

8. Dice Game (Exercise) In a board game a pair of dice (one is 6 sided and the other is 12 sided) is rolled. You win when there is a matching number, or the sum of the numbers rolled is equal to 18. In this problem we would like to build a VI that will do the following: i) Rolls the pair of dice every 100ms and displays the numbers rolled ii) A digital indicator displays the number of times dice rolled iii) An LED glows when you win iv) A digital indicator displays the number of wins v) Program stops after exactly100 rolls.

Great Architecture clips

IIT kanpur,Aerospace (Aerodynamics) Direct Ph,D interview experiences.

INTERVIEW EXPERIENCE IN AEROSPACE(aerodynamics) AT IIT KANPUR FOR DIRECT PhD  My self *********, I have completed my B.Tech (from Mechanical Engineering) in 2018. I wrote GATE 2018 as well as 2019 and got a decent score. B.tech CGPA was moderate. for PhD programme your GATE score and CGPA not really matter a lot it is just a screening and cutoff purpose, but the thing is you have to really passionate about what you are going to do, you need to really strong in your basic engineering and math, Especially in-depth knowledge of your subject of the domain(not necessary bounded by GATE syllabus)  Domains are broadly classified as AERODYNAMICS     Fluid mechanics, Aerofoil theory, Basic of Turbulences, Heat Transfer Flow separation and    Engineering Maths, FLIGHT MECHANICS AND CONTROL   Mechanics, Fluid mechanics, Aerofoil theory, some control system, Engineering Maths. STRUCTURE AND AEROELASTICITY   Strength of materials, Theory ...
