Correct Answer: strain is proportional to the distance from the neutral axis
4. 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
5. 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.
10. When a body is subjected to direct tensile stresses (?x and ?y ) in two mutually perpendicular directions, accompanied by a simple shear stress ?xy , then in Mohr's circle method, the circle radius is taken as
