A close coil helical spring of mean diameter

*D*consists of*n*coils of diameter*d*. If it carries an axial load*W*, the energy stored in the spring, is27.

A simply supported beam

*A*carries a point load at its midspan. An other identical beam*B*carries the same load but uniformly distributed over the entire span. The ratio of the maximum deflections of the beams*A*and*B*, will be28.

The maximum deflection of a simply supported beam of span

*L*, carrying an isolated load at the centre of the span ; flexural rigidity being*EI*, is29.
