The slope is the pitch divided by the developed circumference of the helix which is pi x diameter.
Pitch = pi x diamter x slope

How do you mark holes on pitch circle diameter?
The best way is to calculate the number of degrees of separation you wish to have between the holes. The formulas can be found in any geometry text. One can then mark the spots with a pen or marker before making the actual holes.
How do you mark 72 a number hole in 1385 mm pitch circle diameter?
72 holes = 5 degree spacings (5 x 72 = 360) The centre-to-centre distance of the holes is c = 60.4129mm. You can either mark out the holes using a protractor at 5 degree spacings, or you must calculate the distance 'c' given above. c = sqrt ( 2 x r2 - ( 2 x r2 x cos a )) r = radius = 1385/2 = 692.5mm a= angle = 5 degrees
How is pitch and frequency related?
Pitch is basically frequency... High Frequency = High Pitch Low Frequency = Low Pitch Definitions Frequency: The number of waves that pass a unit of time(like seconds,minutes,hours,and etc.) Pitch: The highness or lowness of a sound 5th Grade Stuff.... ^_^ =D
What another word for roof slope?
Pitch
How are frequency and pitch related?
Well, the higher the frequency is the higher the pitch. They both travel with sound waves and they both have a big role in how sound travels.
What is the pitch of an amino acid -helix?
The pitch of a helix is defined as the distance along the helical axis that results in one full turn of the helix. In the case of amino acid helices, this value is an average value of about 5.5 Angstroms. A-DNA B-DNA Z-DNA Right-handed helix Right-handed Left-handed Short and broad Long and thin Longer and thinner Helix Diameter 25.5A 23.7A 18.4A Rise / base-pair 2.3A 3.4A 3.8A Base-pair / helical turn ~ 11 ~ 10 ~ 12 Helix pitch 25A 34A 47A Tilt of the bases 20 deg -1 deg -9 deg Also see http://tigger.uic.edu/classes/phys/phys461/phys450/ANJUM04/
Formula module in helical gear?
the module of a helical gear is calculated in the same way of that of a spur gear: module=pitch diameter / no of teeth the module of a helical gear is calculated in the same way of that of a spur gear: module=pitch diameter / no of teeth
What is the formula in getting the diametral pitch of helical gears?
External diameter / number of gear = pitch
How do you find length of helical stirrups for piling?
Length of helical stirrups = 3.14*d*n + p*n d= diameter n= no. Of turne ( = height/ pithh) p = pitch of helical stirrups
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 Pitch of a DNA duplex?
bp/turn of DNADNA have this periodicity in which each base is separated from the other by 36 degree angle so for the base to take a comlete round ( 360 degree ) it will take about 10 bases to do so.To clarify the answer...the residues in the double helix are 3.6 Angstroms apart by a rise of 1.5 Angstroms...if you want to calculate the pitch then you multiply these values and you will get 5.4 Angstroms...this is the pitch of the DNA double helix.
How do you find helical angle?
If you mean find the helical angle, alpha, using the pitch, p, with a shaft of radius, R, at the root of the teeth then: alpha= arctan( p /(2R) ) Otherwise, if you mean find the helical angle while designing a gear, it is quite complicated and requires the knowledge of various parameters such as the maximal torque, speed, material, etc.

What is the axial length of alpha helix containing 78 amino acids?
the pitch of a alpha helix is o.54 nm , that is the distance between two points at the same horizontal position in a helix if is held up right. there are 3.6 aa per turn. therefore if there are 78 aa then Lengthhelix= (78 /3.6)* 0.54 nm
How do you calculate the pitch of a spiral spring?
You can tell if a spiral spring pitch is normal by this equation; 0.2*D < p < 0.4*D. However, you can calculate a spiral spring pitch by l = πDn, A = πd2 /4.
How do you calculate the pitch circle diameter?
circle diameter minus center of pitch cirlce raius
What conditions mus hold true if two gears are to mesh properly?
Tooth size, style and pitch must be the same. And if the gears are helical they must have the same twist, in opposite directions.
