A magnetic particle clutch is a special type of electromagnetic clutch which does not use friction plates. Instead, it uses a fine powder of magnetically susceptible material (typically stainless steel ) to mechanically link an otherwise free-wheeling disc attached to one shaft, to a rotor attached to the other shaft.
Gust lock on a rudder. A gust lock on an aircraft is a mechanism that locks control surfaces and keeps open aircraft doors in place while the aircraft is parked on the ground and non-operational. Gust locks prevent wind from causing unexpected movements of the control surfaces and their linked controls inside the aircraft, as well as aircraft ...
An immersed area of 0.1 m 2 at 1 m lever length at a boat speed of 2.5 m/s (about 5 knots) and 5° angle of attack already generates a moment of 180 N⋅m, when the oar has a NACA0012 profile. [7] The steering force of the servo oar is transmitted to the main rudder typically involving an arrangement of two lines and four or more rolls to guide ...
The rudder attaches to the skeg and is steered by cables attached to it. In select sweeping boats, typically fours and eights, a coxswain will control the rudder, while in sculling boats and some sweeping boats, especially pairs, the rudder will be controlled with toe-steering. [4] A skeg typically consists of a flat piece of metal or plastic. [5]
The clutch slips until the input and output RPMs are matched. This happens relatively quickly typically (0.2 - 2 sec). When the current is removed from the clutch, the armature is free to turn with the shaft. Springs hold the friction disks away from each other, so there is no contact when the clutch is not engaged, creating a minimal amount of ...

The flap rudder is designed to improve the effective lift generated by the rudder and hence improve the manoeuvrability of the craft. The rudder consists of two or more sections which move relative to each other as helm is applied and the angle of the main or driven section moves, thus the shape of the rudder changes dynamically as the angle of helm is changed.
Sprint kayak is a type of canoe sprint held on calm water. The paddler is seated, facing forward, and uses a double-bladed paddle pulling the blade through the water on alternate sides to propel the boat forward. Kayak sprint has been in every summer Olympics since it debuted at the 1936 Summer Olympics. [1]
