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...

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

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

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

    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..

Use of formula loop plot of graph y=sin(x)/x and y=sin(x^2)/x in LabVIEW

1. Formula loop Using formula loop compute y for the following two functions: 𝑦1 = sin(x)/x and 𝑦2 = sin(x2)/x where x varies from 0 to 10 in step of 0.05. Plot 𝑦1 & 𝑦2 vs. x in a single XY graph. Use For Loop and Formula loop for this problem.
