4. In a thick cylindrical shell subjected to an internal pressure (p), the tangential stress is always a tensile stress where as the radial stress is a compressive stress
Correct Answer: the ratio of its length to the least radhis of gyration is less than 80.
6. A body is subjected to a direct tensile stress of 300 MPa in one plane accompanied by a simple shear stress of 200 MPa. The maximum shear stress will be
7. 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.
8. The bending moment diagram for a cantilever beam of length l and carrying a gradually varying load from zero at the free end and w per unit length at the fixed end is a parabolic curve.
