Euler's and Rankine's crippling load for hollow circular section/Column/ Strength of Materials

[@gawadesahilvikas9483]

Sir how did u find the value of A plz explain

[@pravinspatil]

A = cross-secional area
Calculated in this video

Sir how to find thickness in Hollow circular giving rankines for mula

[@pravinspatil]

t = D-d/2
t = thickness
D = external diameter
d = internal diameter

[@balasubramani960]

K = 12.58

Sir what is the value of small n in moment of inertia in eulers crippling load?

[@pravinspatil]

This is not n
This is Π
