Bar linkages kit
- Four-bar linkages
- Straight line linkages – Watt’s straight line, Chebyshev, Peaucellier-Lipkin, Hart’s inversor, Robert’s and Hoeken’s
- Ackermann steering
- Work panel and curriculum available separately
This kit includes a selection of over 20 perforated bars of different lengths and pivots or 'joints' to allow students to create an unlimited choice of linkages. Students assemble the bars and joints in any arrangement and note how the linkage converts movement from one form to another, for example rotary motion to linear motion. Bar linkages are one of the most basic mechanisms used in mechanical engineering. The kit includes magnetic 'wipeable' sheets and holders for non-permanent markers so the students can trace the relative movements of the linkages or joints. The kit introduces students to key engineering terms such as four-bar linkages, rotary and linear movement and planar linkages.
Essential base unit and kit must be ordered separately.
