Question

Answer the given statements as True or False. If the statement is false, correct it so it becomes a true statement.

1. The neutral axis can be found at a distance ‘y’ (where y>0) from the centroidal axis of a
member.

2. The centre of curvature can be found at a radial distance (rho) from the neutral axis of a
member in pure bending.

3. When developing generalized equations for stress transformations, we must consider
stresses on only the horizontal and vertical faces.

4. Shear strain is defined as the angle between two line segments that were originally parallel
to each other.

5. In biaxial bending, the principle of superposition can be used to add bending components
about more than one principal axis.

6. When determining average shear stress along a horizontal section, we are to assume a
uniform and linear shear stress distribution.

7. In beams, to express internal moments and shears, positive sign convention on the face to
the right of the cut section with internal shear represented as a downward force (V) and
internal moment (M) represented as a counter-clockwise moment.

8. In Mohr’s circle, the average stress of the element is at the center of the circle.

9. Shear stress components of adjacent planes are equal and opposite.

10. Buckling is a sudden large displacement parallel to the direction of loading.
