Question

A column has effective length as 20unit. Determine Euler load of EI = 1000 unit.

(a) 24.67 unit

(b) 10 unit

(c) 40 unit

(d) 50.99 unit

The question was posed to me in final exam.

This interesting question is from Structural-Analysis Fundamentals in portion Structures and Loads of Aircraft Design

Answer 1

The correct option is (a) 24.67 unit

To explain: Euler load = \(\frac{\pi^2 EI}{(Effective \,length)^2}\)

= \(\frac{\pi^2*1000}{20^2} \) = 24.67 unit.
