The figure below shows a gear lover bracket of a milling machine

Draw full size:

(a)a sectional elevation on XX;

(b)an end elevation looking in the direction of arrow Y.

Show far leading dimensions.

N.B   Hidden details are not to be indicated. Assume suitable dimensions where necessary.

 

OBSERVATION

MECHANICAL DRAWING

a.Sectional Elevation

Candidates were expected to

(i)draw to full size
(ii)draw six(6) center lines
(iii)draw five (5) long horizontal lines draw five short horizontal lines draw six( 6) long vertical lines draw two(2) short vertical lines draw two (2) holes
(iv)draw two centre lines
(v)draw two(2) radii
(vi)draw ten(lO) fillets
(vii)section the upper part
(viii)section the lower part
(ix)show four (4) dimensions
(x)write section X - X
(xi)draw full size draweight(8)centre lines draw five (5) horizontal lines draw twelve (12) vertical lines draw four inclined lines
(xii)draw three(3) radii
(xiii)draw one curve of interpenetration draw three (3) holes
(xiv)draw two (2) concentric circles draw sixteen (16) fillets
show four (4) loading dimensions


Less than 50% of the candidates attempted the question. Their performance was fairly good but riot as good as those of the candidates who attempted the building option. Generally, candidates seemed to have general phobia for the Mechanical drawing. This could be because they are not taught well in that aspect.
