1. The bending moment in the centre of a simply supported beam carrying a uniformly distributed load of w per unit length is Azero Cwf/4 Bwf/2 Dwf/8 2. When a thin cylindrical shell is subjected to an internal pressure, there will be A a decrease in diameter and length of the shell Ban increase in diameter and decrease in length of the shell Ca decrease in diameter and increase in length of the shell Dan increase in diameter and length of the shell 3. In a simple bending theory, one of the assumption is that the material of the beam is isotropic. This assumption means that the A normal stress remains constant in all directions B.normal stress varies linearly in the material Celastic constants are same in all the directions D.elastic constants varies linearly in the material 4. The bending moment of a cantilever beam of length I and carrying a gradually varying load from zero at free end and w per unit length at the fixed end is at the fixed end. A.wl/2 Cw/2 B.wl D.wf/6 5. In the below figure, the stress corresponding to point D is Im 0 Strain Stress- A.yield point stress B. breaking stress Qultimate stress Delastic limit 6. The Poisson's ratio for cast iron varies from A.0.21 to 0.27 B0.20 to 0.30 C0.31 to 0.34 D.0.32 to 0.42 7. The resultant stress on an inclined plane which is inclined at an angle 0 to the normal cross- section of a body which is subjected to a direct tensile stress (a) in one plane, is D A sin e Ba cos 0 Ca sin 20 D.a cos 20 8. If percentage reduction in area of a certain specimen made of material 'A' under tensile test is 60% and the percentage reduction in area of a specimen with same dimensions made of material 'B' is 40%, then A.the material A is more ductile than material B the material B is more ductile than material A the ductility of material A and B is equal Dthe material A is brittle and material B is ductile 9. The maximum deflection of a cantilever beam of length / with a uniformly distributed load of w per unit length is (where W=wl) WP A3 El B wp C-16 EI WP 48 EI 4 10. When shear force at a point is zero, then bending moment is point. A.zero C,maximum minimum D.infinity at that
