6. The actual neutral axis of a reinforced cement concrete beam is based on the principle that the moment of areas of compression and tension zones at the neutral axis are equal.
7. A column of length (l) with both ends fixed may be considered as equivalent to a column of length __________ with one end fixed and the other end free.
8. If there is a fall in the temperature of a composite body, then a member having greater coefficient of linear expansion will be subjected to compressive stress.
10. The hoop stress in a riveted cylindrical shell of diameter (d), thickness (t) and subjected to an internal pressure (p) is (where ? = Efficiency of the riveted joint)
