Cams, gears and pulleys

A collection of resources for GCSE Design and Technology that support the teaching of rotary systems (I.e. Cams and followers, gears and pulleys).

Links and Resources

Levers and linkages, gears, pulleys and cams

This collection of classroom presentations, student worksheets and student revision activities support the teaching of:

  • types of motion (I.e. reciprocating, oscillating, linear, rotary)
  • gears (I.e. bevel, idler, gear trains
  • pulleys
  • levers (I.e. first order, second order, third order) and linkages (I.e. push / pull)
  • cams and followers (I.e. eccentric, snail, oval)

Design and make projects to teach mechanisms

Produced by the Technology Enhancement programme (TEP), these materials help students to understand, design and prototype mechanisms (including levers, gears and linkages). The resource also supports students to work through some of the mathematical concepts involved in calculating gear ratio.

Students are challenged to make a series of mechanisms to meet specific design briefs:

  • 'easy open' jar clamp
  • pantograph engraver
  • stone tumbling machine
  • picture frame clamp
  • wire frame automaton

Study files are also included and these allow students to research and practice important techniques and topics. The areas covered include: design, researching mechanical systems (including four bar linkage, cam and cam follower, crank-slider, friction, stiffness, electric motors, smart wire.

Testing a pulley system

n this resource students are asked to test the operation of pulley systems and calculating their mechanical advantage. Suggested learning outcomes include:

  • To understand what is meant by mechanical advantage.
  • To be able to calculate the mechanical advantage of pulley systems.
  • To perform suitable tests on how a pulley system functions.

Modelling pulley systems

This resource investigates modelling and constructing pulley systems designed to lift loads. Suggested learning outcomes include:

  • To be able to recognise and describe the main parts of a pulley system.
  • To understand how a pulley system can reduce the effort needed to lift a load.
  • To model and construct different types of pulley systems.
