Question

A sturdy column with a hollow rectangle shape is made of steel. 150mm length and 70mm width, thickness of steel=6mm.

E=200Gpa

-what is the max slenderness ratio if the column is pinned at both ends 3m long?

-what is the critical load if the column is pinned at both ends and is 3m?

-what is critical load if the column is fixed at both ends and is 7m?

Answer 1

a). Maximum slenderness ratio if the column is pinned at both ends 3m long = 104.84.

b). Critical load if column is pinned at both ends 3 m long = 4.482 × 10^17 N.

c). Critical load if the column is fixed at both ends, 7m long = 3.293 × 10^17 N.

(Please give a thumbs up ).
