Question

A symmetrical section subjected to a load inclined to its principal axis will produce

• A. Pure bending
• B. Symmetrical bending
• C. Unsymmetrical bending
• D. Torsion

Hint:

If the load acts \[ \boxed{ \begin{aligned} \text{Along a principal axis} &\rightarrow \text{Symmetrical bending} \text{Inclined to principal axes} &\rightarrow \text{Unsymmetrical bending} \end{aligned} } \]

Answer 1

The Correct Option is C

Step 1: Recall the condition for symmetrical bending. Symmetrical bending occurs when the applied load acts in the plane of a principal axis of the cross-section.

Step 2: Determine the effect of an inclined load. If the load is inclined to the principal axis, \[ \boxed{ \text{bending takes place about both principal axes simultaneously.} } \] This type of bending is called \[ \boxed{\text{Unsymmetrical bending}.} \] Therefore, \[ \boxed{\text{Unsymmetrical bending}} \] is the correct answer. Thus, \[ \boxed{(C)} \] is the correct answer.
