How do you define slenderness ratio?

Correct Answer : Option (A) :   euler load

Explanation : Euler load is defined as the highest compression load which will not cause the elastic column buckling. Euler load is also termed as critical load. Bernoulli’s theorem is used for fluids. Newtonian fluid are those fluids which follow the Newton’s law of viscosity.

Correct Answer : Option (C) :   3.16

Explanation : Given, column is supported by pin at both the end.
Now, slenderness ratio = effective length/ radius of gyration = 10/3.16 = 3.16.

Correct Answer : Option (D) :   Ratio of column’s effective length to c/s radius of gyration

Explanation : The ratio of column’s effective length to c/s radius of gyration can be termed as slenderness ratio. The effective length of the column is determined based on the end constraints such as pinned joints, fixed ends etc.
