Exercise : Strength of Materials - Section 6

11.

A steel bar 2 m long, 20 mm wide and 10 mm thick is subjected to a pull of 2 kN. If the same bar is subjected to a push of 2 kN, the Poission's ratio of the bar in tension will be __________ the Poisson's ratio for the bar in compression.

12.

A square beam and a circular beam have the same length, same allowable stress and the same bending moment. The ratio of weights of the square beam to the circular beam is

13.

A thin cylindrical shell of diameter (

*d*), length (*l*) and thickness (*t*)is subjected to an internal pressure (*p*). The hoop stress in the shell is14.

When a body is subjected to a direct tensile stress (σ) in one plane, then tangential or shear stress on an oblique section of the body inclined at an angle θ to the normal of the section is
