Paper 1
October/November 2005
2 hours 40 minutes
Additional Materials:
A2 Drawing Paper (1 sheet)
Standard Drawing Equipment
READ THESE INSTRUCTIONS FIRST
Print your Centre number, candidate number and name at the bottom right-hand corner of your Drawing
Paper.
Use both sides of the paper for your answers.
Do not use staples, paper clips, highlighters, glue or correction fluid.
Answer five questions.
Answer not more than three questions from any one section.
Unless otherwise stated, strictly geometrical methods must be used, solutions are to be drawn full size and
no dimensions are required. All construction lines must be shown clearly, but lines which are parallel to,
perpendicular to or inclined at angles of 30°, 45° or 60° to other lines may be drawn without showing
construction lines.
At the end of the examination, fasten all your work securely together.
The number of marks is given in brackets [ ] at the end of each question or part question.
All dimensions are in millimetres unless otherwise stated.
This document consists of 9 printed pages and 3 blank pages.

Fig. 3 shows the outline of a mechanism, in which a circular disc rolls without slipping along a
horizontal plane HP. The link OA is rigidly attached to the circular face of the disc. A is pin jointed
to the link AB, which is constrained at B to slide along OX which is parallel to the horizontal plane.
Draw the locus of point R as the disc rolls clockwise from the position shown to the point where
OA has turned through 210°.

the two given views;
[3]
(ii)
an end elevation.
[2]
(b) Determine the shape for the development of the fume extractor hood, and indicate on the
development the bend lines required for its construction.
