This form of power transmission is called a Z-drive because the rotary motion has to make two right angle turns, thus resembling the letter "Z". This name is used to differentiate the arrangement of drive to that of the L-drive. It does not refer to an electric motor in a rotating pod.
Form-fit connections are created by the interlocking of the connecting components. For example, the lid cannot slip sideways away from the pot because both interlock at the edge. On the other hand, a round lid can be rotated while sitting on the pot, because there is no form-fit against the rotation.
A rudder operates by redirecting the fluid past the hull or fuselage, thus imparting a turning or yawing motion to the craft. In basic form, a rudder is a flat plane or sheet of material attached with hinges to the craft's stern, tail, or afterend. Often rudders are shaped to minimize hydrodynamic or aerodynamic drag.
Advantages of the sterndrive system versus inboards include simpler engineering for boatbuilders, eliminating the need for them to design propshaft and rudder systems; ease of trailering and shallow water maneuvering (with the drive trimmed up); also, a significant space savings with the engine mounted all the way aft, freeing up the boat's ...
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 ...
A Florida man is accused of stabbing his estranged girlfriend up to 70 times during a fatal break-in - exactly one month after he was nabbed for assaulting the victim and ordered to stay away from ...
The American Express Global Business Travel’s Air Monitor 2025 report predicts domestic travel within the U.S. and travel from the U.S. to most other regions will rise by 3% to 4% in 2025 ...
Typical trim tabs on aileron, rudder and elevator. Trim tabs are small surfaces connected to the trailing edge of a larger control surface on a boat or aircraft, used to control the trim of the controls, i.e. to counteract hydro- or aerodynamic forces and stabilise the boat or aircraft in a particular desired attitude without the need for the operator to constantly apply a control force.
