The forces in the members of simple trusses, may be analysed byDeselect Answer Graphical method Method of joints Method of sections All the above 2. The ratio of circumferential stress to the longitudinal stress in the walls of a cylindrical shell, dueDeselect Answer 2 1½ 1 ½ 3. The assumption in the theory of bending of beams is:Deselect Answer Material is homogeneous Material is isotropic Young's modulus is same in tension as well as in compression All the above 4. Maximum principal stress theory for the failure of a material at elastic point, is knownDeselect Answer Guest's or Trecas' theory St. Venant's theory Rankine's theory Von Mises' theory 5. Slenderness ratio of a long column, isDeselect Answer Area of cross-section divided by radius of gyration Length of column divided by least radius of gyration Area of cross-section divided by least radius of gyration Radius of gyration divided by area of cross-section 6. If a three hinged parabolic arch, (span l, rise h) is carrying a uniformly distributed load w/unit length over the entire span,Deselect Answer B.M. will be zero throughout Horizontal thrust is wl2/8h S.F. will be zero throughout All the above 7. The yield moment of a cross section is defined as the moment that will just produce the yield stress inDeselect Answer The outer most fibre of the section The inner most fibre of the section The neutral fibre of the section The fibre everywhere 8. A body is said to be in equilibrium ifDeselect Answer It moves horizontally It moves vertically It rotates about its C.G. None of these 9. The strain energy due to volumetric strainDeselect Answer Is directly proportional to the volume Is directly proportional to the square of exerted pressure Is inversely proportional to Bulk modulus All the above 10.
