A propeller is a type of fan that transmits power by converting rotational motion into thrust. A pressure difference is produced between the forward and rear surfaces of the airfoil-shaped blade, and a fluid is accelerated behind the blade. Propeller dynamics, like those of aircraft wings, can be modelled by Bernoulli's principle and Newton's third law. Most marine propellers are screw propellers with fixed helical blades rotating around a horizontal axis or propeller shaft.
A simple machine is a mechanical device that changes the direction or magnitude of a force. In general, they can be defined as the simplest mechanisms that use mechanical advantage to multiply force. Usually the term refers to the six classical simple machines which were defined by Renaissance scientists:
A drill is a tool primarily used for making round holes or driving fasteners. It is fitted with a bit, either a drill or driver, depending on application, secured by a chuck. Some powered drills also include a hammer function.
Wesley Eric Weston Jr., better known by his stage name Lil' Flip, is an American rapper. He embarked on his musical career as a freestyle and battle rapper before earning a record deal with Suckafree Records in 1999. Lil' Flip is best known for his singles "The Way We Ball", "Game Over" and "Sunshine".
A twin-screw steamer (TSS) is a steam-powered vessel propelled by two screw propellers, one on either side of the plane of the keel.
Chopped and screwed, is a technique of remixing hip hop music which developed in the Houston hip hop scene in the early 1990s. This is accomplished by slowing the tempo down to between 60 and 70 quarter-note beats per minute and applying techniques such as skipping beats, record scratching, stop-time, and affecting portions of the music to make a "chopped-up" version of the original.
A linear actuator is an actuator that creates motion in a straight line, in contrast to the circular motion of a conventional electric motor. Linear actuators are used in machine tools and industrial machinery, in computer peripherals such as disk drives and printers, in valves and dampers, and in many other places where linear motion is required. Hydraulic or pneumatic cylinders inherently produce linear motion. Many other mechanisms are used to generate linear motion from a rotating motor.
A jackscrew, or screw jack, is a type of jack that is operated by turning a leadscrew. It is commonly used to lift moderately heavy weights, such as vehicles; to raise and lower the horizontal stabilizers of aircraft; and an adjustable supports for heavy loads, such as the foundations of houses.
A leadscrew, also known as a power screw or translation screw, is a screw used as a linkage in a machine, to translate turning motion into linear motion. Because of the large area of sliding contact between their male and female members, screw threads have larger frictional energy losses compared to other linkages. They are not typically used to carry high power, but more for intermittent use in low power actuator and positioner mechanisms. Common applications are linear actuators, machine slides, vises, presses, and jacks.
A butt joint is a technique in which two pieces of material are joined by simply placing their ends together without any special shaping. The name 'butt joint' comes from the way the material is joined together. The butt joint is the simplest joint to make since it merely involves cutting the wood to the appropriate length and butting them together. It is also the weakest because unless some form of reinforcement is used it relies upon glue alone to hold it together. Because the orientation of the wood usually presents only one end to long grain gluing surface, the resulting joint is inherently weak.
A linear-motion bearing or linear slide is a bearing designed to provide free motion in one direction. There are many different types of linear motion bearings.
