In sailing, a boom is a spar (pole), along the foot of a fore and aft rigged sail, that greatly improves control of the angle and shape of the sail. The primary action of the boom is to keep the foot flatter when the sail angle is away from the centerline of the boat. The boom also serves as an attachment point for more sophisticated control lines.
In crane terminology, slewing is the angular movement of a crane boom or crane jib in a horizontal plane. The term is also used in the computer game Microsoft Flight Simulator wherein the user presses a key and he or she can rotate and move the virtual aircraft along all three spatial planes .
A rudder angle indicator is a device used to indicate the present position of the rudder blade, usually fitted near the Ship's wheel on the bridge and in the engine control room. [1] Rudder angle indicator of the MS Nordstjernen (1956) Rudder angle indicator
A jibboom (also spelled jib-boom) is a spar used to extend the length of a bowsprit on sailing ships. [1] It can itself be extended further by a flying jib-boom. [1] The heel (i.e. rear and lower) end of the flying jib-boom is attached to the jib-boom, and the heel of the jib-boom to the bowsprit.
The SLI measures the angle and extension of the boom along with the load weight and compares this with the manufacturer's specifications to determine if the lift is safe. [2] A safe load indicator has the capability of detecting the angle, weight of load lifted, and ground radius of any lifting device.
It is a rigid strut that extends obliquely upward from the boom to the mast, exerting a force that pushes down on the boom. As the fixing point of the gnav on the boom is hauled inwards towards the mast, the downward force on the boom increases. A gnav offers more uncluttered space beneath the boom when compared to a vang.
For example, the spinning rotor may be suspended in a fluid, instead of being mounted in gimbals. A control moment gyroscope (CMG) is an example of a fixed-output-gimbal device that is used on spacecraft to hold or maintain a desired attitude angle or pointing direction using the gyroscopic resistance force.
