Compression, Tension, Shear, Bending, Torsion
|
|
|
|
|
|
|
1)
Two basic forces: Compression & Tension
|
|
2) A combination of compression and tension: Shear & Bending
|
|
3) A combination of the above four forces: Torsion
|
|
|
|
|
|
|
|
Compression: compression is the direct expression of the
force, which pushes
|
|
|
everything
towards the center of an object.
|
|
|
|
|
|
|
|
Tension: the opposite of compression; the force which pulls
everything away from
|
|
|
|
the center; where there is a compressive force, there must be a
tensile force.
|
|
|
|
|
|
|
Shear: shear is present, when two forces are thrusting in
opposite directions but
|
|
|
offset
and slide past each other.
|
|
|
|
|
|
Bending:
is found between the pulling of tension and the pushing of compression.
|
|
|
|
|
|
|
Torsion: a result of all the other four forces. Torsion is
twist. Torsion is actually a
|
|
|
specialized
bending, a circular bending.
