A steel plate d x b is sandwiched rigidly between two timber joists each D x B/2 in section. The moment of resistance of the beam for the same maximum permissible stress σ in timber and steel will be (where Young's modulus of steel is m times that of the timber).

The ratio of crippling loads of a column having both the ends fixed to the column having both the ends hinged, is

Maximum strain theory for the failure of a material at the elastic limit, is known as

A cantilever of length L is subjected to a bending moment M at its free end. If EI is the flexural rigidity of the section, the deflection of the free end, is

The maximum bending moment for a simply supported beam with a uniformly distributed load w/unit length, is
