Ancient boat building methods can be categorized as one of hide, log, sewn, lashed-plank, clinker (and reverse-clinker), shell-first, and frame-first. While the frame-first technique dominates the modern ship construction industry, the ancients relied primarily on the other techniques to build their watercraft. In many cases, these techniques ...
Strip-built, or "strip-plank epoxy", is a method of boat building. [1] Also known as cold molding, the strip-built method is commonly used for canoes and kayaks, but also suitable for larger boats. The process involves securing narrow, flexible strips of wood edge-to-edge around temporary formers.
Energy shield from the game Second Life. In speculative fiction, a force field, sometimes known as an energy shield, force shield, energy bubble, or deflector shield, is a barrier produced by something like energy, negative energy, dark energy, electromagnetic fields, gravitational fields, electric fields, quantum fields, telekinetic fields, plasma, particles, radiation, solid light, magic, or ...
Boat building is the design and construction of boats (instead of the larger ships) — and their on-board systems. This includes at minimum the construction of a hull , with any necessary propulsion, mechanical, navigation, safety and other service systems as the craft requires.
The one sheet boat (OSB, cf. oriented strand board) is an outgrowth of the stitch and glue technique. The OSB is a boat that can be built using a single sheet of 4 foot by 8 foot plywood (1.22 m × 2.44 m). Some additional wood is often used, for supports, chines, or as a transom, though some can be built entirely with the sheet of plywood ...
The Nydam boat, an early example of clinker construction. The earliest example of ship and boat building using overlapped planking joined with metal fastenings is in an extended logboat from Björke in Sweden. This dates to c. 310 AD. The Nydam boat is an almost complete example of a boat built with clinker construction. It has overlapping ...
The higher the angular momentum, the greater the resisting force of the gyro to external torque (in this case more ability to cancel boat roll). A gyroscope has three axes: a spin axis, an input axis, and an output axis. The spin axis is the axis about which the flywheel is spinning and is vertical for a boat gyro.
Force field (technology), a barrier made up of energy, plasma or particles to protect a person, area or object from attacks or intrusions or as a means of containment or confinement; Force field, a region in the spinal cord that causes limbs to exert a consistent force depending on the limbs' position
