  • Shows how three popular mechanisms convert motion
  • Includes Scotch Yoke, Crank and Slider and Quick Return Mechanism
  • Work panel and curriculum available separately

This kit includes three popular mechanisms which fit on to a work panel for experiments in conversion of motion from linear to rotary or rotary to linear. These include the Scotch Yoke (sometimes called 'donkey crosshead' or 'slotted link'), the Crank and Slider and the Quick Return mechanisms. Students test each mechanism to see how it works and note the differences in the way that each mechanism converts the motion. The three mechanisms are the same as those used in real applications, such as combustion engines, power assisted valves or fluid pumping systems. Each has a unique way of converting motion, shown by the experiments. The kit introduces students to key engineering terms such as reciprocating motion, rotary to linear motion and linear to rotary motion. Worksheets, guidance notes and lecturer notes (with answers) needed for typical experiments are supplied with the work panel.

Essential base unit and kit must be ordered separately.

Learning objectives/experiments include:

  • Conversion of motion using the 'Scotch Yoke' (or slotted link)
  • Conversion of motion using the Quick Return mechanism
  • Conversion of motion using the Crank and Slider
