A helix is a shape like a corkscrew or spiral staircase. It is a type of smooth space curve with tangent lines at a constant angle to a fixed axis. Helices are important in biology, as the DNA molecule is formed as two intertwined helices, and many proteins have helical substructures, known as alpha helices. The … Meer weergeven The pitch of a helix is the height of one complete helix turn, measured parallel to the axis of the helix. A double helix consists of two (typically congruent) helices with the same axis, differing by … Meer weergeven In mathematics, a helix is a curve in 3-dimensional space. The following parametrisation in Cartesian coordinates defines a particular helix; perhaps the simplest equations for one is $${\displaystyle x(t)=\cos(t),\,}$$ As the Meer weergeven An example of double helix in molecular biology is the nucleic acid double helix. An example of conic helix is the Corkscrew roller coaster at Meer weergeven • Alpha helix • Arc spring • Boerdijk–Coxeter helix Meer weergeven WebThe helix angle of helical gears β is generally selected from the range 6,8,10,12,15,20 degrees. The larger the angle the smoother the motion and the higher speed possible however the thrust loadings on the supporting bearings also increases. In case of a double or herringbone gear β values 25,30,35,40 degrees can also be used.
