Question

The cross section at right is made of 2024-T3 (Ftu=62 ksi, E=10.5 Msi,Ec=10.7 Msi) aluminum clad sheet. Dimensions of the angle areb1=1.25", b2=1.75", t1=0.050", & t2=0.080". If the angle is 20" long, and the ends can be considered pinned, determine the critical buckling allowable Pcr for the angle & the allowable buckling stress σcr.

Answer 1

See explaination

Step-by-step explanation:

Given that

the cross section at right is mode 2024-T3

Ftu=62 ksi

E=10.5 Msi

Ec=10.7 Msi

the angle b1=1.25"

b2=1.75"

t1=0.050"

t2=0.080"
