-
If D and d are external and internal diameters of a circular shaft respectively, its polar moment of inertia, is
-
A steel bar 20 mm in diameter simply-supported at its ends over a total span of 40 cm carries a load at its centre. If the maximum stress induced in the bar is limited to N/mm2, the bending strain energy stored in the bar, is
-
The deflection curve for the portal frame shown in the given figure is
-
A close coil helical spring when subjected to a moment M having its axis along the axis of the helix
-
For beams breadth is constant,
-
A body is said to be in equilibrium if
-
Keeping breadth constant, depth of a cantilever of length l of uniform strength loaded with uniformly distributed load w varies from zero at the free end and
-
The force in CD of the truss shown in given figure, is
-
The deflection of a uniform circular bar of diameter d and length l, which extends by an amount e under a tensile pull W, when it carries the same load at its mid-span, is
-
The ratio of the stresses produced by a suddenly applied load and by a gradually applied load on a bar, is
