1. Two bars of different materials and same size are subjected to the same tensile force. If the bars have unit elongation in the ratio of 2:5, then the ratio of modulus of elasticity of the two materials will be
5. A simply supported beam 'A' of length l, breadth b and depth d carries a central load W. Another beam 'B' of the same dimensions carries a central load equal to 2 W. The deflection of beam 'B' will be __________ as that of beam 'A'.
6. The given figure shows the Mohr's circle of stress for two unequal and like principal stresses (?x and ?y) acting at a body across two mutually perpendicular planes. The resultant stress is given by
7. When a body is subjected to bi-axial stress i.e. direct stresses (?x) and (?y) in two mutually perpendicular planes accompanied by a simple shear stress (?xy), then maximum shear stress is
8. In order to avoid sliding of masonry dam, the force of friction between the dam and soil should be at least __________ the total water pressure per metre length.
9. 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.
10. When a bar of length l and diameter d is rigidly fixed at the upper end and hanging freely, then the total elongation produced in the bar due to its own weight is (where w = Weight per unit volume of the bar)
