CONTENTS
This is a book of 165 pages containing a large and comprehensive selection of useful
look-up information on strength of materials, manufacturing processes, ergonomics etc. enabling pupils and students to get access to data that is not otherwise available in a
single publication or which is often presented in a highly technical form. The handbook
also includes:• worked examples showing how quantitative data can be applied in design
and technology• TEP data sheets on electronics components• a special section called
'Small Miracles of Technology'
This last section illustrates a variety of 'throwaway' products as examples of advanced engineering. Because they are readily available, the products selected - including, pull-top can; stapler; PET bottle; ball pen; cassette tape - are an excellent starting point for the National Curriculum’s 'Products and Applications'.
