Leaf springs only allow motion up and down. An axle can be positioned with two leaf springs and won't move left-right or forward and back. A spiral spring requires another device to stabilize it, torque bars, A frames mounted to K bars, or struts, because the spring alone will allow motion in all directions.
Helical
is helical coil and coil spring are the same
Of or pertaining to, or in the form of, a helix; spiral; as, a helical staircase; a helical spring.
Because it handles both tensile (Expansion) load & Compression Loads...
a balance that measure weight by the tension on a helical spring
a helical spring has N turns of coil of diameter D, and a second spring made of same material and of same wire diameter has N/2 turns of coil of diameter 2D. if stiffness of first spring is k, then stiffness of second spring is
helical spring
Protein is a chemical family name. Its shape may be helical. But a helical shape is of a spring type item shape.
How do calculate spiral length of Spiral rings
The angle which the axis of the spring wire makes with the horizontal line is known as helix angle.
Helical springs are the typical, common, wound springs used in tension or compression. The term 'helical' comes from the spring being a helix- the wire is wound around a mandrel, advancing along the length of the mandrel as it is wound.
A spring balance is a device wherein an object to be weighed is attached to the end of a helical spring. Gravity is a factor in using this calibrated scale.
