Specification 1.5.4, 1.5.5, 1.5.7, 3e · Paper 1
Repeated backwards-and-forwards movement along a straight line.
Revise: CamsWith a guide keeping the follower on a straight path, this converts rotary motion into reciprocating motion: repeated movement up and down, or backwards and forwards.
Repeated backwards-and-forwards movement along a straight line, such as a follower moving up and down.
Describe both the input and output: a rotating cam produces reciprocating motion of a guided follower.
Distinguish reciprocating motion, which follows a straight path, from oscillating motion, which swings about a pivot.
Create a free account to keep every note you open and track your progress.
Repeated backwards-and-forwards motion along a straight path.
Component 1
Revise: Mechanical Components and DevicesIn a sewing machine, a belt can transfer rotation from a motor to the machine’s shaft; other mechanisms then produce the needle’s reciprocating motion. The belt itself does not directly make the needle move up and down.
Repeated back-and-forth movement along a straight path.
