Question

True (1) Moment diagrams will be at a maximum or minimum when the shear False force is zero. True False (2) Torsion causes a member to contract or expand along its axis. True False (3) The neutral axis of a cross-section is located at the cross-section's shear center. True False (4) The stress concentration factor, K, is used in the calculation of normal bending stress when a member has a sudden change in cross-section True False (5) Shear flow refers to the bending moment transferred between parts of a built-up shape.

Explanation / Answer

1)True. Shear force is given by slope of bending moment diagram.If bendingn moment is maximum,shear force is zero

2)False. Torsion just twists the member.It does not change axial length of member

3)False. The neutral axis is located at cross section's geometric centroid

4)False

5)False. Shear flow refers to shear force transferred between parts of a built up section
