The needles (pointers) of a dual tachometer indicator installed in a helicopter are said to “married” when one needle is exactly on top of the other.
One needle is driven by a tachometer generator on the engine and the other by a generator on the transmission that senses the speed of the rotor. When the rotor-drive clutch is fully engaged and there is no slippage, the needles are married.

The neutral axis of a piece of material being bent is a plane within the material along which there is no stress. The neutral axis is located approximately halfway (actually 44.5% of the thickness of the material) from the inside of the bend. The material on the outside of the bend is under a tensile stress, and that on the inside is under a compressive stress. There is no stress along the neutral axis.

The normal length of time an object or material can be expected to keep its usable characteristics if it is stored and not used. Many products, such as batteries, rubber seals, shock cord, and certain types of finishing materials, have a date stamped on them. This date relates to the shelf life. If these products are not used by the date stamped on them, there is a possibility that they will not function as they should.
