- Meaning of O-slash in data sheet about gear diameter?
I have this data sheet for a stepper motor: The pitch diameter of the pinion attached to it is listed as "Ø6" What unit is this? Looking at the wikipedia page for Ø it seems like this is just a no
- Lowercase phi (φ) seemingly used for diameter in diagram instead of Ø?
On a technical drawing for resistors, the lead diameter was given as $\\varphi 0 55\\text{mm}$ Since they also specify the wire is 24 SWG, and 24 SWG is a diameter of 0 559mm, did they simply use φ
- mechanical engineering - AutoCAD circle dimension annotation meanings . . .
What do the following annotations mean in this AutoCAD drawing mean? R1 25 TYP (circle hole Left) 2XØ1 0 (circle hole Right) Ø1 25 (circle hole Bottom) Based on those annotations, what is the diam
- What does this line with cross means in the blueprint?
The diameter symbol (⌀) (Unicode character U+2300) is similar to the lowercase letter ø, and in some typefaces it even uses the same glyph, although in many others the glyphs are subtly distinguishable (normally, the diameter symbol uses an exact circle and the letter o is somewhat stylized)
- mechanical engineering - Understanding hole specifications . . .
4 x means it applies to the four instances that look similar on the drawing Ø 5 means the hole diameter (drill size) is 5mm “Thru all” is added here to remove the requirement for a section view to show hole depth You can’t tell by the outlines whether it’s through, or you can see the bottom of the hole M6x1 0 - 6H is the thread and tolerance to be tapped into the drilled hole

- Heater control loops when the primary heat loss is radiative
We're working on a small vacuum test chamber (~150mm ø × 50mm), from room temperature to ~250°C for testing electronic devices It currently uses an old off-the-shelf PID controller, but I've been thinking about the physics behind temperature control in this case
- Parallel vs series springs - Engineering Stack Exchange
I am trying to understand how to simplify a mechanical system of multiple springs where their ends are fixed In this example, kA and kB are effectively in parallel: Is equal to: And so we can co
