- Gradually applied static loads do not change with time their
- The yield moment of a cross section is defined as the moment that will just produce the yield stress in
- Beams composed of more than one material, rigidly connected together so as to behave as one piece, are known as
- At yield point of a test piece, the material
- The load on a spring per unit deflection, is called
- 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
- A load of 1960 N is raised at the end of a steel wire. The minimum diameter of the wire so that stress in the wire does not exceed 100 N/mm² is:
- For beams of uniform strength, if depth is constant,
- A composite beam is composed of two equal strips one of brass and other of steel. If the temperature is raised
- A compound bar consists of two bars of equal length. Steel bar cross -section is 3500 mm²and that of brass bar is 3000 mm². These are subjected to a compressive load 100,000 N. If Eb = 0.2 MN/mm² and Eb = 0.1 MN/mm², the stresses developed are:
