Maximum tension will be at 5°. Half of the mass of each leaf rests on the ground, the other half at the top pivot, making 80 kg total at...

The fan lowers the pressure at the inlet. Air from all directions begins to flow toward the fan, turning gradually as it accelerates...

What was the capacity of the old pump in cubic feet of free air per minute? How does that compare with the replacement? Did the...

Forget my previous post. I have fixed a few bugs and got the uA709 / LM709 working as a 5kHz voltage follower. Attached are the .asc and...

You need to comment out the *.subckt and *.ends to make the nodes and components in the model available on that schematic page. You can...

There are two ways. 1. You can simply copy the spice text into a .op spice directive box, then place that on the schematic page. 2. You...

Also, thicker wire will hold more ice. Ice on overhead wire is bad news. Heavy ice on wires alone is not necessarily why they come down...

There are several reasons why extra high voltage lines are not insulated. If insulation was present on EHV lines, corona discharge could...

Laminar flow cabinets circulate air through filters. UV light is used to sterilise the filters, to prevent colonisation of the filters...

The path length for a flat braid? The golden braid.

Several processes - one is that at some point "all questions were already answered", quite often it was enough to google for problem to...

The clock designer appears to have used the sidereal month, not the synodic month, in their design calculations. Sidereal month =...

Any SPICE will do with that code, but LTspice, now from ADI, is probably the best at the moment, and is free. Also, subscribe to...

Here is an LTspice model for the uA/LM709. At the end it defines the transistors used as all having the same specifications. * LM709...

Do you have the full circuit for the uA709, or just the simplified diagram ? Resistor values are here: https://lh.pe/file/UA709CN(1).pdf
