When loads are applied proportionately to a frame structure containing its members in one plane, the structure is called

The ratio of strengths of solid to hollow shafts, both having outside diameter D and hollow having inside diameter D/2, in torsion, is

The minimum number of rivets for the connection of a gusset plate, is

In a loaded beam, the point of con-traflexture occurs at a section where

The radius of gyration of a rectangular section is not proportional to

In the cantilever truss as shown in below figure, the horizontal component of the reaction at A, is

If a rectangular beam measuring 10 x 18 x 400 cm carries a unformly distributed load such that the bending stress developed is 100 kg/cm2. The intensity of the load per metre length, is

The number of points of contraflexure in a simple supported beam carrying uniformly distributed load, is

A cantilever carries is uniformly distributed load W over its whole length and a force W acts at its free end upward. The net deflection of the free end will be

If the shear force along a section of a beam is zero, the bending moment at the section is

If the width b and depth d of a beam simply supported with a central load are interchanged, the deflection at the centre of the beam will be changed in the ratio of

The tensile force required to cause an elongation of 0.045 mm in a steel rod of 1000 mm length and 12 mm diameter, is (where E = 2 x 106 kg/cm2)

For a simply supported beam of length L, the bending moment M is described as M = a (x - x3/L2), 0 ≤ x < L; where a is a constant. The shear force will be zero at
