What is the purpose of the helix angle in relation to aeroplane propellers?
maximum thrust is obtained.
Is an angle be negative?
Yes. Sometimes in mathematics, it is useful to have negative angles. You can increase or decrease an angle by 360 degrees (or 2*pi radians) without changing the characteristics of the angle. Thus, for example, an angle of 30 degrees is equivalent to an angle of -330 degrees.
Can an angle be negative in trigonometry?
no because the only way degrees can be negative is in temperature.
What does it mean when an angle is negative?
An angle is a measure of turn. the amount of turn is the magnitude, measured in degrees, and direction of turn can be clockwise or anti-clockwise. A positive angle turns in an anti-clockwise direction while a negative angle turns in a clockwise direction.
Can angle measurements be negative?
Yes, although it may seem strange. Conventionally, on a Cartesian plane, angles are measured in an anticlockwise dirction, from the x-axis. Consequently, an angle in the clockwise direction could be considered a negative angle. It might be simpler to think of an angle of 359 degrees as one of -1 degrees, instead. Sometimes you need to subtract one angle from another and in that context, a negative measure for the angle is implicit.
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.
What materials are machined by low helix angle drill bit?
low helix angle drill bits are used for machining hard materials
What happens when reamer rotates backwards?
The reamer will be dull soon. It shurely happens after ~ 3 reverse turns due to friction of metal chips (back angle of reamer's blade does not cut). It is very difficult to physically destroy an reamer by such way but there are 3 problems: 1. Dull reamer will "scrap" instead of "cut". Surface will be more rough and hole will be more inaccurate (bad roundness). 2. You HAVE to re-gring dull reamer to sharp its blades. 3. Re-grinded reamer will have smaller diameter - reamer will be inaccurate and inappropriate soon. Example: Typical diameter of new (metric) 10H8(+0,022) reamer is 10(+0,01;+0,015). Diameter of re-grinded reamer will be 10(+0,005;+0,01). After next re-grinding reamer will be 10+0,005 , next time 9,995+0,005, next time 9,99+0,005, 9,985+0,005 and so on. Reamer marked 10H8 with outer diameter 9,99+0,005 is inappropriate(9,995 is _smaller_ than 10. IT IS VERY BAD due to possible fit error).
What is the melting point for reamer?
A reamer is a tool, not a material. The melting point would depend on what material the reamer is made of.
When did Robert Reamer die?
Robert Reamer died in 1938.
When was Robert Reamer born?
Robert Reamer was born in 1873.
What is cos of a negative angle?
The cosine function is an even function which means that cos(-x) = cos(x). So, if cos of an angle is positive, then the cos of the negative of that angle is positive and if cos of an angle is negative, then the cos of the negative of that angle is negaitive.
What is the purpose of the helix angle in relation to aeroplane propellers?
maximum thrust is obtained.
When was Cory Reamer born?
Cory Reamer was born on 1987-05-06.
When was Keith Reamer born?
Keith Reamer was born in 1960, in New Jersey, USA.
How do you find the complement of a negative angle?
To find the complement of a negative angle, you first need to determine its positive equivalent by adding 360 degrees to the negative angle. Once you have the positive angle, you can then find its complement by subtracting the angle from 90 degrees. This will give you the complement of the negative angle in the range of 0 to 90 degrees.
What is a reamer used to accomplish?
A reamer concentrically enlarges a hole in a thin-ish piece of material.
