rigid arm conveyor
A conveyor in the form of an endless belt or chain to which are attached projecting arms or shelves which carry the materials.
A conveyor is any materials-handling machine designed to move individual articles; such as, solids or free-flowing bulk materials over a horizontal, inclined, declined, or vertical path of travel with continuous motion.
rigid body, rigid-body motion, rigid-body dynamics
1. In mechanics, a body which does not change its shape or size regardless of the force applied to it; that is, the relative position of its component particles is absolutely fixed in positon relative to each other.
2. An actual body whose behavior approaches that of an ideal rigid body; such as, a steel beam.
3. An idealized extended solid whose size and shape are definitely fixed and remain unaltered when forces are applied.
The rigid body assumption is a mathematical convenience that is useful and gives correct results for many important phenomena.
rigid copper coaxial line
In electromagnetism, a coaxial cable in which the central conductor and the outer conductor are formed by joining rigid pieces of copper.
A mechanical device which joins, or fastens, shafts that are connected so their axes are directly in line and normally stay that way.
A structural steel skeleton frame in which beams and columns and end connections of all members are rigidly connected without using hinges, so that the angles they make with each other do not change.
