Learning Opportunities: To introduce pupils to basic mechanisms / mechanical movement such as cams, cranks, linkages etc. To develop basic design and research skills; To develop manufacturing skills through a range of workshop processes. Activity Description: Theory: The pupils study mechanisms for approximately 3 x 35min periods; Manufacture: To manufacture a number of the models parts from set working drawings; Applied Design: To design and manufacture the body of the toy. Use templates / jigs where necessary.
A Mechanical Toy Monkey Design Opportunities: a)Show using concept sketches two alternative designs for the monkey’s body b)Explain using graphics the mechanical solution to making the toy move when the crank is rotated. Include notes / annotation. c)Show how adjustments may be made to the mechanism to make the monkey move higher? d)Design a base for the mechanical monkey from acrylic sheet measuring ---- x ------ e) Show examples of where an interference-fit and a clearance-fit is used in this project? f) Name suitable materials for the base and body of this toy design? g)State a suitable protective finish for this project?
