A beam column...

Question

A beam column is alternately bent either (1) in single curvature, or (2) in double curvature. The secondary moments induced are to be compared. These are indicated $S M_{1}$ and $S M_{2}$ as per the conditions (1) and (2) respectively

S M_{1} > S M_{2}

Solution

The correct option is A $S M_{1} > S M_{2}$
(a)
The member of Beam Column is subjected to axial compression with bending.

Since, $Δ_{1} > Δ_{2}$ so secondary moment $P Δ_{1} > P Δ_{2}$ . It means $S M_{1} > S M_{2}$ .
