2. The pull required to tear off the plate per pitch length is (where p = Pitch of rivets, t = Thickness of plates, and ?t, ? and ?c = Permissible tensile, shearing and crushing stresses respectively)
5. When a body is subjected to three mutually perpendicular stresses, of equal intensity, the ratio of direct stress to the corresponding volumetric strain is known as
Correct Answer: strain is proportional to the distance from the neutral axis
9. A thick cylindrical shell having ro and ri as outer and inner radii, is subjected to an internal pressure (p). The minimum tangential stress at the outer surface of the shell is
10. 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.
