Pitch:
- The distance from one point on a thread to the same point on the adjacent thread.
- The reciprocal of the pitch is the number of threads per inch.
Thread:
- Formed on the screw in a helix.
- Helix is the path of a point traveling around an imaginary cylindrical such that its axial and circumferential velocities maintain a constant ratio.
- When a single helix is making a screw, it is called a single start thread.
- In a single start thread, the lead and pitch are the same.
- In the case of two start threads, one thread is wound within the other exactly in the middle. This enables the lead of the helix to increase without increasing the pitch.
- Lead = Pitch × Number of the starts
Explanation:
The distance from a point on a thread to the corresponding point on the next thread of a screw is called pitch.
Additional Information Flute:
- It is made in the form of an open cylindrical air column about 66 cm long.
- Its fundamental pitch is middle C (C4) and it has a range of about three octaves to C7.
- Sound is produced from a flute by blowing onto a sharp edge, causing air enclosed in a tube to vibrate.
