The ratio of crippling loads of a column having both the ends fixed to the column having both the ends hinged, is
YOUR ANSWER : ?
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
YOUR ANSWER : ?
A simply supported beam carries varying load from zero at one end and w at the other end. If the length of the beam is a, the maximum bending moment will be
YOUR ANSWER : ?
At any point of a beam, the section modulus may be obtained by dividing the moment of inertia of the section by
YOUR ANSWER : ?
A composite beam is composed of two equal strips one of brass and other of steel. If the temperature is raised
YOUR ANSWER : ?
The yield moment of a cross section is defined as the moment that will just produce the yield stress in
YOUR ANSWER : ?
A masonry dam (density = 20,000 N/m³) 6 m high, one metre wide at the top and 4 m wide at the base, has vertical water face. The minimum stress at the base of the dam when the reservoir is full, will be
