# Engineering Drawing Tutorial Solution I

### SOLUTION FOR TUTORIAL NO. 4 (DESCRIPTIVE GEOMETRY II)

**T 4.1) **A line AB 75 mm long is inclined at 45 degree
to the HP and 30 degree
to the VP. Its end B is in
the HP and 40 mm in front of the VP. Draw its projections.

**T 4.2) **Draw the projections of a line AB, 90 mm long, its midpoint M being 50 mm above
the HP and 40 mm in front of the VP. The end A is 20 mm above the HP and 10 mm
in front of the VP.

**T 4.3) **The top view of a 75 mm long line measures 65 mm while the length of its front view
is 50 mm. Its one end is in the HP and 12 mm in front of the VP. Draw the projections
of AB and determine its inclinations with the HP and the VP.

**T 4.4) **A line 65 mm long has its one end 20 mm above the HP and 25 mm in front of the
VP. The other end is 40 mm above the HP and 65 mm in front of the VP. Draw the
projections of the line and determine its inclinations with the HP and the VP.

**T 4.5) **Reproduce the given view of the lines and determine the true lengths using the
auxiliary view method.

** T 4.6) **Reproduce the given view of the lines and determine the true lengths using the
revolution method.

** T 4.7) **Determine the shortest distance between the point C and line AB.

** T 4.8) **Reproduce the given views of the plane and draw the view showing the true size and
shape.

** T 4.9) **Determine the angle between the line MN and non-transparent plane ABC. Also
determine the visible portion of the line.

** T 4.10) ** Determine the shortest distance between the lines MN and ST.

** T 4.11) ** Determine the angle between the planes ABC and BCD.
