  • Displacement is the distance traveled between two points
  • Unconstrained movement in a mechanism means that one link is held fixed and the movement of any other link to a new position will not cause each of the other links to move to definite predictable positions
  • A rigid link in a machine is a link whose deformations are so small that they can be neglected in determining motions of the various other links
  • A kinematic link consists of a number of pairs of elements connected by links
  • Coplanar motion refers to a body, or a series of bodies, where component particles are moving in the same plane or in a parallel plane
  • Velocity is the time rate of motion of a point along its path, or the rate at which a point is approaching or receding from another point in its path
  • Pure mechanism deals with the motions and forms of the parts of a machine, and the manner of supporting and guiding them, independent of their strength
  • A machine is a combination of resistant bodies arranged so that the mechanical forces of nature can be compelled to produce some effect or work accompanied with certain determinate motions
  • A link is any body which has motion relative to another, serving to transmit forces from one piece to another or to cause motion or control motion
  • A frame in a machine refers to the surfaces of contact between two pieces that have relative motion, one of which supports or partially supports the other
  • A higher pair in a mechanism refers to contact which exists at a point or along a line
  • Translation motion means a body has motion with the same velocity, as regards both speed and direction, when all its component particles have the same velocity
  • Machine design involves the calculation of the forces acting on different parts of the machine
  • Oscillation is a term applied to reciprocating circular motion, such as that of a pendulum
  • A path is a point moving in space that describes a line, which may be rectilinear or curvilinear
  • Continuous motion is when a point continues to move indefinitely in a given path in the same sense
  • Linear acceleration is the time rate of change of linear velocity
  • A crank is part of a machine that is stationary and supports the moving members
  • Turning bodies in a machine may be defined as an arm rotating or oscillating about an axis
  • A closed pair in a mechanism is another term for a lower pair
