01. A simply supported beam of length l is loaded with a uniformly distributed load of w per unit length. The maximum deflection is and lies at the centre of the beam.

02. A simply supported beam is one which is supported on more than two supports.

03. If the diameter of pressure vessel is 15 times the wall thickness, the vessel is said to be a thick shell.

04. The perpendicular distance between the centre lines of the successive rows, is called pitch.

05. 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.

06. The direct stress, across a principal plane, is known as principal stress.

07. In a beam of uniform strength, the bending stress developed is constant and is equal to the allowable stress at every section of the beam.

08. The critical neutral axis of a reinforced cement concrete beam is based on the principle that the neutral axis is situated at the centre of gravity of a given section.

09. A thick pressure vessel is always used for the generation of steam, as it can withstand high pressures.

10. A simply supported beam 'A' of length l, breadth b and depth d carries a central point load W. Another bream 'B' has the same length and breadth but its depth is doubled. The deflection of beam 'B' will be double as compared to beam 'A'.

11. 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.

12. Poisson's ratio is the ratio of linear stein to the volumetric strain.

13. The maximum bending moment for a simply supported beam with a gradually varying load from zero at both ends and w per metre at the centre, lies at the centre of a beam.

14. In a riveted joint, when the rivets in the adjacent rows are staggered in such a way that every rivet is in the middle of the two rivets of the opposite row, the joint is said to be diamond riveted.

15. In a cantilever beam of length l subjected to a uniformly distributed load of w per unit length, the maximum deflection lies at the fixed end.

16. When there is no increase or decrease in shear force between two points, it indicates that there is no change in the bending moment between these points.

17. In order to know whether a column is long or short, we must know its slenderness ratio.

18. A beam supported at its both ends is not a simply supported beam.

19. When the shear force diagram between any two points is an inclined straight line, it indicates that there is a uniformly varying load between the two points.

20. For the two shafts connected in parallel and subjected to twisting moment, the angle of twist of each shaft will be same.
