Observation

Candidates were required to draw the full size of the given views of a machine.  Very few candidates attempted this question and their performance was above average.
Candidates were expected to:

Front Elevation

(i)         draw in first angle projection;
(ii)        draw full-size;
(iii)       draw the outline;
(iv)       draw 3 centre lines;
(v)        draw face – A;

1. draw the web – W;
2. draw the vertical hole in face – A (hidden);
3. draw 2 – cutting planes X – X and Y – Y;
4. draw face – B;
5. draw FACE – C/horizontal hole;
6. draw the base, threaded and countersunk holes.

Sectional Plan  Y – Y

(i)         draw in first angle projection;
(ii)        draw full-size;
(iii)       draw 6 centre lines;
(iv)       draw the outline;

1. draw the web – W;
2. draw 2 – threaded holes/2 – countersunk holes;
3. draw the base;
4. draw face – B;
5. section web – W;
6. show hidden details.

.
Sectional End Elevation X – X

(i)         draw in first angle projection;
(ii)        draw full-size;
(iii)       draw the outline;
(iv)       draw the 4 – centre lines;

1. draw face – A ;
2. draw face – B;
3. draw shaft – C;
4. draw the base/threaded holes;
5. draw the horizontal hole in face – C;
6. draw the vertical hole in face – A;
7. section the face – A;
8. section face – C;
9. section the base;
10. show the web – in hidden;
11. draw neatly.
