[Boatanchors] Tower Construction

[Brian A Clarke]

Hi Mike,

It's Hooke's Law - not Poisson's ratio.
Strain [the deflection] = k [the coefficient of elasticity] x the stress
[the
force you apply].

To claim that something doesn't deflect is nonsense.

The actual coefficient of elasticity depends of the strength of the
material, eg, Young's modulus, and the shape of the structure - built-in,
pinned, etc.

There is no simple formula that applies to all structures; you would be
well advised to get a structural engineer to look at each particular
installation. Such a person will also be able to calculate Euler's ratio.
