YOUR ANSWER : ?
YOUR ANSWER : ?
A short column (30 cm × 20 cm) carries a load P 1 at 4 cm on one side and another load P2at 8 cm on the other side along a principal section parallel to longer dimension. If the extreme intensity on either side is same, the ratio of P1 to P2 will be
YOUR ANSWER : ?
A bar L metre long and having its area of cross-section A, is subjected to a gradually applied tensile load W. The strain energy stored in the bar is

YOUR ANSWER : ?
The maximum bending moment for a simply supported beam with a uniformly distributed load w/unit length, 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 : ?
The locus of the moment of inertia about inclined axes to the principal axis, is
YOUR ANSWER : ?
If E, N, K and 1/m are modulus of elasticity, modulus of rigidity. Bulk modulus and Poisson ratio of the material, the following relationship holds good
