    AA jet and Military helicopter collide over Potomac

    You mean actually doing like she was told to do, when told to pass behind the plane? Because she was directed to pass behind the plane, meaning she needed to wait for it to cross in front of her. You really like posting in circles, circles, circles.

    AA jet and Military helicopter collide over Potomac

    Hold where exactly? Short of the path of the wrong plane she was watching? How does the pilot be precise about their "hold" position when hurtling through a dark night sky?

    Excitation current on induction motor as a generator via VFD

    Exciting current for the motor comes from the DC bus. Never from the AC source. The input on the AC source is only the real power to rotate the motor. The post edison123 made isn't even that dramatic a difference. I've seen it much larger when spinning an unloaded motor on a VFD. The big...

    120/240V 1P-3W, 100A Service to Very Remote Building

    Around here, it's common for the rural customers to put in their own poles and overhead line for the utility to feed directly off the power line at the road. I believe the transformer can either be leased or purchased, but it's possible the utility provides it on the customer pole instead of at...

    Fast switching SSR SPDT (Solid state Single-Pole-Double Throw) Relay

    Why not just build the circuit with transistors? It's not that complex.

    Dominican Republic Nigh Club Roof Collapse

    This e-house type unit looks like something rather heavy for the roof.

    KW, KVA, KVAR relationship

    The prime mover (engine) produces kW. Changing the kVAR only does not change the kW load on the prime mover hence doesn't change the amount of fuel used. You can't change just the kVAR in practice, but assuming you could it doesn't affect the fuel used. The kW is used by customers and by...

    KW, KVA, KVAR relationship

    The prime mover load produces the kW. Changing the VARs produced doesn't affect the engine load. Correcting the power factor could cause a reduction in kW due to less cable or transformer losses with the lower current, but it is a secondary effect. A bigger kW change might be possible by...

    Semi Hauling Excavator Hits Bridge over I-10 in New Mexico

    Not a surprising to me at all. It's rather impossible to spread the load while rolling if you can't raise the box in motion.

    AA jet and Military helicopter collide over Potomac

    Hmm, so there was a minimum distance. Imagine that... Even without a fixed number, far enough away you don't crash would be the minimum distance to stay back, not trying to pass 25' under the landing gear.

    AA jet and Military helicopter collide over Potomac

    The minimum separation distance sets where they were not supposed to go. They were not able to simply stay below 200' and do as they please. If they were, then they could have just dropped lower and buzzed the landing gear of the plane without a care in the world.

    Suggestions Needed: Thermal switch on live MV heatsink

    Float it to the same circuit as the gate drive for the SCR cathode connected to that heatsink then convert to an optical signal to send back to the controller.

    AA jet and Military helicopter collide over Potomac

    They were given instructions, not just information. If you actually read my posts instead of trying to find ways to defend your crap, you'd see that I (me, myself) posted that they had to hold and that I NEVER posted anything saying ATC told them to hold. So, get over it. ATC told them to cross...

    Switchgear busbars sizing

    I don't know of any rule that requires the main busbar to be greater than the sum of the loads. I often see switchgear where the loads are greater than the bus size, these system often have backup equipment such that all loads don't all operate at the same time. I've also seen main-tie-main...

    AA jet and Military helicopter collide over Potomac

    They must WAIT for the plane to crash. Call it whatever you want, but quit nitpicking my terminology, which I called HOLD, as in they can't go past a certain point until the plane passes. I guess I should have written a whole paragraph about how they were supposed to maneuver around as the plane...

    AA jet and Military helicopter collide over Potomac

    What are they supposed to be doing when they're told to keep visual separation and pass behind? Do circles? Go up and down?

    AA jet and Military helicopter collide over Potomac

    They do, the helicopter was supposed to hold and wait for the plane to pass. It waited for the wrong plane. The error was allowing the helicopter to control their location and deciding when to pass through via visual separation. If there were well defined holding points and the ATC had to...

    flame sensor

    Use a gas valve with a thermocouple.

    Highway overpass collapses in South Korea

    Were they bringing that beam placing machine out over a bunch of beams without a deck? Sure looks like the beams rolled over and then everything fell.

    Toronto place crash

    I wouldn't blame them for not wanting to buy fuel in Toronto but instead carry enough to get back to Minneapolis. I'd expect there is a decent savings there.
