If a constant section beam is subjected to a uniform bending moment throughout, its length bends to
The length of a column, having a uniform circular cross-section of 7.5 cm diameter and whose ends are hinged, is 5 m. If the value of E for the material istonnes/cm2, the permissible maximum crippling load will be
A cantilever beam rectangular in cross-section is subjected to an isolated load at its free end. If the width of the beam is doubled, the deflection of the free end will be changed in the ratio of
A simply supported wooden beamcm long and having a cross sectioncm xcm carries a concentrated load, at the centre. If the permissible stress ft =kg/cm2 and fs =kg/cm2 the safe load is
When equal and opposite forces applied to a body, tend to elongate it, the stress so produced, is called
The maximum resistance against rotation, is offered by the weld at a point
A cylinder is said to be thin if the ratio of its thickness and diameter, is less than
A joint of a frame is subjected to three tensile force P, Q and R equally inclined to each other. If P istonnes, the other forces will be
In a bar of large length when held vertically and subjected to a load at its lower end, its own-weight produces additional stress. The maximum stress will be
At either end of a plane frame, maximum number of possible bending moments, are
In a three hinged arch, the third hinge is generally kept at
A simply supported beam (l + 2a) with equal overhangs (a) carries a uniformly distributed load over the whole length, the B.M. changes sign if
If a three hinged parabolic arch carries a uniformly distributed load on its entire span, every section of the arch resists.
The phenomenon of slow extension of materials having constant load, i.e. increasing with the time is called
Stress in a beam due to simple bending, is
For structural analysis of forces, the method refers to
The shear force on a simply supported beam is proportional to

In a three hinged arch, the bending moment will be zero
The shape of the bending moment diagram over the length of a beam, carrying a uniformly increasing load, is always
A bending moment may be defined as :
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 type of butt joints in common use, is :
In a three hinged arch, the shear force is usually
