Question
Name the four types of mechanical motion.
Answer
Linear, rotary, oscillating and reciprocating.
Question
What is the difference between oscillating and reciprocating motion?
Answer
Both reverse. Reciprocating motion travels back and forth along a straight line; oscillating motion swings back and forth along an arc about a pivot.
Question
Give an example of each of the four motions.
Answer
Linear — a drawer or a lift. Rotary — a fan or a drill bit. Oscillating — a pendulum or a windscreen wiper. Reciprocating — a piston or a jigsaw blade.
Question
Why should an input be written as a motion rather than a part?
Answer
Because a mechanism is defined by what it converts. "The handle" says nothing; "rotary motion applied by hand at the handle" tells you what has to come out the other end.
