Calculate Euler Buckling Load with Different End Fixity Conditions

[thebest99]

a steel rod, 40mm in diameter and 1.00m long is pinned at each end

calculate the euler bucking load

Answer:

using PE = pie sqaured 210x10cubed kN/mm x 1.25 x 10power 5mm to the 4 divided by 1000mm sqaured

=259.1kN

b) indentify three other possible end fixity conditions for the rod and demonstrate how the Euler buckling load will be effected in each case

i have pinned -fixed, PE=2.04pie sqaured EI divided by L sqaured

fixed -fixed , PE= 4pie sqaured EI dived by L sqaured
and fixed free, PE= quater pie sqaured EI divide by L sqaured

can someone help with question b.

thnak you

What sort of help are you looking for? You've identified 3 other end conditions and noted how it affects the critical buckling load.

believe i have to do the calculations too for the equations

Plug and chug.
