StarInfo/Allen/!Ignotum/Formulae/Formulae/Soli

This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.

Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

F=kx
Known as Hooke's law, where:
F=tension in a material (N)
k=spring constant for the material (N/m)
x=extension of the material (m)

stress=F/A
Where:
F=tension in a material (N)
A=cross-sectional area or material (m�)
Units: N/m�

strain=x/l
Where:
x=extension of the material in tension
l=original length of material
Note: It has no units, it is merely a
ratio
Young modulus=stress/strain
Young modulus is a way of measuring the
strength of a material independant of its
size, length, area etc.
Units: N/m�

E=�kx�
Where:
E=elastic strain energy (J)
k=spring constant for the material (N/m)
x=extension of the material (m)

E/V=� stress � strain
Where:
E/V=elastic strain energy per unit volume
