Strength Of Materials

The shear force of a cantilever beam of length l and carrying a gradually varying load from zero at the free end and w per unit length at the fixed end is _________ at the fixed end.

When a bar of length ‘l’ and diameter ‘d’ is rigidly fixed at the upper end and hanging freely, then the total elongation produced in the bar due to its own weight is (where w = Weight per unit volume of the bar)

The slenderness ratio is the ratio of

A simply supported beam 'A' of length ‘l’, breadth ‘b’ and depth ‘d’ carries a central load ‘W’. Another beam 'B' of the same dimensions carries a central load equal to 2W. The deflection of beam 'B' will be __________ as that of beam 'A'.

The polar modulus for a solid shaft of diameter (D) is

The bending moment in the center of a simply supported beam carrying a uniformly distributed load of w per unit length is

The simply supported beam 'A' of length ‘l’ carries a central point load ‘W’. Another beam 'B' is loaded with a uniformly distributed load such that the total load on the beam is ‘W’. The ratio of maximum deflections between beams 'A' and 'B' is

The rectangular beam 'A' has length ‘l’, width ‘b’ and depth ‘d’. Another beam 'B' has the same length and depth but width is double that of 'A'. The elastic strength of beam 'B' will be _________ as compared to beam ‘A’.

Rivets are generally specified by

The ductility of a material __________ with the increase in percentage reduction in area of a specimen under tensile test.
