Identify the property that changes as a function of the geometrical dimensions of a section in structural materials.

Which of the following terms represents the torque that produces a twist of one radian in a shaft of unit length?

A rectangular section of width 250 mm and height 400 mm is subjected to a shear force of 45 kN. The magnitude of maximum shear stress develops in the section would be

The power transmitted by a circular shaft subjected to a torque of 6 kNm and rotating at a speed of 200 rpm is

The ratio of maximum bending stress in the two sections subjected to same bending moment having the following dimension

Section 1 = 200×600 mm

Section 2 = 400×600 mm

The design criteria as per maximum shear strain energy theory is

(All symbols have their usual meaning)

A cantilever of beam of span l is fixed at one end, the other end resting freely on the middle of a simply supported crossbeam of the same span and section. If the cantilever beam is now loaded with a uniform load of w per unit length, find the reaction at the free end offered by the cross beam.

Which of the following methods is NOT used for finding deflection of beam?

A cantilever beam of span L carries a uniformly distributed load of w kN/unit length. What is the maximum deflection occurring in the beam? (Take E as the modulus of elasticity and I as the moment of inertia of the beam section)

The property of a material to resist indentation on its surface is known as
