Question

Column has length of 1.2 m and radius of gyration as 1.5m. Determine slenderness ratio. Consider column is fixed at one end free at other end.

(a) 1.6

(b) 7.8

(c) 98

(d) 12.45

I had been asked this question by my school principal while I was bunking the class.

My question is taken from Structural-Analysis Fundamentals in division Structures and Loads of Aircraft Design

Answer 1

Right answer is (a) 1.6

The explanation: For, given column which is fixed at one end and free at other effective length L = 2*1.2m = 2.4m.

Now, slenderness ratio = effective length / radius of gyration = 2.4/1.5 = 1.6.
