What is angle of helix in helical spring?
The angle which the axis of the spring wire makes with the horizontal line is known as helix angle.
Why is the helix angle of a reamer negative?
The helix angle of reamer is negative because to make the reamer more regid so that the reamer can withstand the vibration during reaming
What is the purpose of the helix angle in relation to aeroplane propellers?
maximum thrust is obtained.
How do screws do work?
Screws have a helix design, that drills into the wood, and also holds materials together.
What did Franklin's data reveal about the structure of DNA.?
The patterns and angle of the X suggested that DNA is a helix consisting of two strands that are a regular, consistent width apart. In a nutshell is was basically had a double helix structure.
What are helicle gears?
helical gears offer a refinement over spur gears. The leading edges of the teeth are not parallel to the axis of rotation, but are set at an angle. Since the gear is curved, this angling causes the tooth shape to be a segment of a helix. The angled teeth engage more gradually than do spur gear teeth. This causes helical gears to run more smoothly and quietly than spur gears. Helical gears can be meshed in a parallel or crossed orientation. The former refers to when the shafts are parallel to each other; this is the most common orientation. In the latter, the shafts are non-parallel. For a crossed configuration the gears must have the same pressure angle and normal pitch, however the helix angle and handedness can be different. The relationship between the two shafts is actually defined by the helix angle(s) of the two shafts and the handedness, as defined: : : Where β is the helix angle for the gear. The crossed configuration is less mechanically sound because there is only a point contact between the gears, whereas in the parallel configuration there is a line contact. Quite commonly helical gears are used with the helix angle of one having the negative of the helix angle of the other; such a pair might also be referred to as having a right-handed helix and a left-handed helix of equal angles. The two equal but opposite angles add to zero: the angle between shafts is zero -- that is, the shafts are parallel. Where the sum or the difference (as described in the equations above) is not zero the shafts are crossed. For shafts crossed at right angles the helix angles are of the same hand because they must add to 90 degrees.
what is the shape of a DNA?
double helix
What is pie helix?
MS says :First of all.......... it is pi-helix and not pie-helix....(how much i knw)The pi helix is an extremely rare secondary structural element in proteins. Hydrogen bonds within an pi-helix display a repeating pattern in which the backbone C=O of residue i hydrogen bonds to the backbone HN of residue i+5. Like the 3.10 helix, one turn of pi helix is sometimes found at the ends of regular alpha helices but pi helices longer than a few i, i+5 hydrogen bonds are not found. The infrequency of this particular form of secondary structure stems from the following properties: the phi and psi angles of the pure pi helix (-57.1, -69.7) lie at the very edge of an allowed, minimum energy region of the Ramachandran (phi, psi) map.the pi helix requires that the angle tau (N-CA-C') be larger (114.9) than the standard tetrahedral angle of 109.5 degrees.the large radius of the pi helix means the polypeptide backbone is no longer in van der Waals contact across the helical axis forming an axial hole too small for solvent water to fill.side chains are more staggered than the ideal 3.10 helix but not as well as the alpha helix.
