Maximum principal stress theory for the failure of a material at elastic point, is known
The maximum bending moment for a simply supported beam with a uniformly distributed load w/unit length, is
Shear centre of a half circular section of radius r and of constant thickness, lies at a distance of x from the centre where x is
Pick up the correct statement from the following:
If D and d are external and internal diameters of a circular shaft respectively, its polar moment of inertia, is
For determining the force in the member AB of the truss shown in the given figure by method of sections, the section is made to pass through AB, AD and ED and the moments are taken about
For calculating the allowable stress of long columns is the empirical formula, known as
The forces acting normally on the cross section of a bar shown in the given figure introduce
A body is said to be in equilibrium if
is the equation of Euler's crippling load if
At yield point of a test piece, the material
The forces in the members of simple trusses, may be analysed by
By applying the static equations i.e. ΣH =ΣV = 0 and ΣM =to a determinate structure, we may determine
The ratio of lateral strain to axial strain of a homogeneous material, is known
If a solid shaft (diametercm, lengthcm, N = 0.8 x 105 N/mm2) when subjected to a twisting moment, produces maximum shear stress ofN/mm2, the angle of twist in radians, is
