8x the Diameter is for an unsupported cable, any less then this and you run the risk of flattening the dielectric plates and degrading the centre conductor. however 3x is acceptable when the cable is supported along it's run through out the bend.

because when you but a capacitor in series the capacity eq will be lower than the smaller one, here we have a capacitor of 3 Farad the question is: "how i must to connect another capacitor for have a total capacitance of 2 Farad?" If you put a capacitor of 6 Farad IN SERIES with a 3 Farad if you apply the correct formula: 1/Cx plus 1/Cy = 1/C equivalent

My humble opinion.No because a radial bearing is also known as a journal bearing so its load is radial, compression should mean that it squishes it.

Ody balsa replied to android811's question ·2d ago

D

The correct option is C. When the card is removed while still installed, you must sit at the same potential as the aircraft structure the assembly is referenced to, so any static charge bleeds away through a controlled low current path instead of discharging through the sensitive component; bonding only to the assembly leaves both of you floating relative to the airframe. Refer to Module 5.12 electrostatic sensitive devices, where grounding personnel to aircraft structure is the specified precaution.

A cold day is better than a hot one because the cold day has more density in air so more lift, and dry because the wet day decrease engine efficiency

Why isn’t B the correct answer

Stavros asked a question ·7d ago

T

It's C. We lean on those ISA numbers all the time when we set altimeters and read engine performance against deviation from standard, 15 degrees C and 1013 millibars at sea level. The whole model is built on average mid latitude air, so 45 degrees is the datum, not the equator.

Why

Prodromos asked a question ·8d ago

C

How else would the nose come up if the tail isn't pushing down harder? It's A, decreasing the tailplane incidence loads the tail down more, so the tail drops and the nose pitches up. Heads up though, the other two options are basically saying the same thing, raising and increasing the incidence, so one of them looks like a typo.
